Abstract
Direct activation of cell-surface receptors is highly desirable for elucidating their physiological roles. A potential approach for cell-type-specific activation of a receptor subtype is chemogenetics, in which both point mutagenesis of the receptors and designed ligands are used. However, ligand-binding properties are affected in most cases. Here, we developed a chemogenetic method for direct activation of metabotropic glutamate receptor 1 (mGlu1), which plays essential roles in cerebellar functions in the brain. Our screening identified a mGlu1 mutant, mGlu1(N264H), that was activated directly by palladium complexes. A palladium complex showing low cytotoxicity successfully activated mGlu1 in mGlu1(N264H) knock-in mice, revealing that activation of endogenous mGlu1 is sufficient to evoke the critical cellular mechanism of synaptic plasticity, a basis of motor learning in the cerebellum. Moreover, cell-type-specific activation of mGlu1 was demonstrated successfully using adeno-associated viruses in mice, which shows the potential utility of this chemogenetics for clarifying the physiological roles of mGlu1 in a cell-type-specific manner. Cell-type-specific activation of receptors is desirable for elucidating their roles in tissues or animals. Here, the authors developed a chemogenetic method for direct activation of mGlu1, a GPCR-type glutamate receptor subtype, and demonstrate its use in mouse brain tissue.

Abstract
Hydration around nucleic acids, such as DNA and RNA, is an important factor not only for the stability of nucleic acids but also for their interaction with binding molecules. Thus, it is necessary to quantitatively elucidate the hydration properties of nucleic acids around a certain structure. In this study, volumetric changes in G-quadruplex (G4) RNA formation were investigated by systematically changing the number of G-quartet stacks under high pressure. The volumetric contribution at the level of each G4 structural unit revealed that the core G4 helix was significantly more dehydrated than the other parts, including the edges of G-quartets and loops. These findings will help in predicting the binding of G4 ligands on the surface of G4, depending on the chemical structure of the ligand and solution environment. Therefore, the preset volumetric parameter provides information that can predict molecular interactions in G4 formations during molecular crowding in cells.

Abstract
Cell surface receptors transmit extracellular information into cells. Spatiotemporal regulation of receptor signaling is crucial for cellular functions, and dysregulation of signaling causes various diseases. Thus, it is highly desired to control receptor functions with high spatial and/or temporal resolution. Conventionally, genetic engineering or chemical ligands have been used to control receptor functions in cells. As the alternative, chemogenetics has been proposed, in which target proteins are genetically engineered to interact with a designed chemical partner with high selectivity. The engineered receptor dissects the function of one receptor member among a highly homologous receptor family in a cell-specific manner. Notably, some chemogenetic strategies have been used to reveal the receptor signaling of target cells in living animals. In this review, we summarize the developing chemogenetic methods of transmembrane receptors for cell-specific regulation of receptor signaling. We also discuss the prospects of chemogenetics for clinical applications.

Abstract
Cell-surface receptors play a pivotal role as transducers of extracellular input. Although different cell types express the same receptor, the physiological roles of the receptor are highly dependent on cell type. To understand each role, tactics for cell-specific activation of the target receptor are in high demand. Herein, we developed an orthogonal activation method targeting metabotropic glutamate receptor 1 (mGlu1), a G-protein coupled receptor. In this method, direct activation via coordination-based chemogenetics (dA-CBC) was adopted, where activation of mGlu1 was artificially induced by a protein conformational change in response to the coordination of a metal ion or metal-ion complex. Our structure-based protein design and screening approach identified mGlu1 mutants that were directly activated by the coordination of Cu2+ or Zn2+, in addition to our previous Pd-complex-sensitive mGlu1 mutant. Notably, the activation of the mutants was mutually orthogonal, resulting in cell-type selective activation in a model system using HEK293 cells.

Abstract
Transmembrane receptors transmit extracellular information into cells. In many cases, protein families are composed of highly homologous subtypes, each of which has unique cellular functions. Therefore, it is highly desired for understanding the physiological roles of the receptor in tissues or animals. However, it is difficult to control the activity of receptors in a cell-type- and subtype-specific manner with high temporal resolution using traditional pharmacological or genetic engineering methods. Recently, chemogenetics has been focused on controlling the cellular signaling in a cell-type-specific manner, which allows for elucidating the function of specific cell types with high temporal resolution. However, conventional chemogenetics are not suitable for understanding the roles of each receptor. Therefore, we have developed a chemogenetic method, termed coordination chemogenetics, in which coordination chemistry and genetic engineering are combined. The coordination chemogenetics enabled artificial activation of ionotropic glutamate receptor (GluA2) and metabotropic glutamate receptor (mGlu1). A palladium (Pd) complex successfully activated mGlu1 in mGlu1(N264H) knock-in mice, demonstrating that endogenous mGlu1 activation is sufficient to evoke a key cellular mechanism of synaptic plasticity that underlies motor learning in the cerebellum. We also expanded the coordination chemogenetics for orthogonal activation of mGlu1 activity using Cu2+, Zn2+, and Pd complexes for analyzing the individual roles of mGlu1 simultaneously. Notably, coordination chemogenetics can be expanded to apply selective inhibition of transmembrane receptors, and the dissociation is much slower than that of conventional inhibitors. Thus, coordination chemogenetics would be a unique method for controlling mGlu1 in a cell-type-specific manner.

Abstract
Proteins are the workhorse molecules performing various tasks to sustain life. To investigate the roles of a protein under physiological conditions, the rapid modulation of the protein with high specificity in a living system would be ideal, but achieving this is often challenging. To address this challenge, researchers have developed chemogenetic strategies for the rapid and selective modulation of protein function in live cells. Here, the target protein is modified genetically to become sensitive to a designer molecule that otherwise has no effect on other cellular biomolecules. One powerful chemogenetic strategy is to introduce a tethering point into the target protein, allowing covalent or non-covalent attachment of the designer molecule. In this tutorial review, we focus on tethering-based chemogenetic approaches for modulating protein function in live cells. We first describe genetic, optogenetic and chemical means to study protein function. These means lay the basis for the chemogenetic concept, which is explained in detail. The next section gives an overview, including advantages and limitations, of tethering tactics that have been employed for modulating cellular protein function. The third section provides examples of the modulation of cell-surface proteins using tethering-based chemogenetics through non-covalent tethering and covalent tethering for irreversible modulation or functional switching. The fourth section presents intracellular examples. The last section summarizes key considerations in implementing tethering-based chemogenetics and shows perspectives highlighting future directions and other applications of this burgeoning research field.

Abstract
Lipids play crucial roles as structural elements, signaling molecules and material transporters in cells. However, the functions and dynamics of lipids within cells remain unclear because of a lack of methods to selectively label lipids in specific organelles and trace their movement by live-cell imaging. We describe here a technology for the selective labeling and fluorescence imaging (microscopic or nanoscopic) of phosphatidylcholine in target organelles. This approach involves the metabolic incorporation of azido-choline, followed by a spatially limited bioorthogonal reaction that enables the visualization and quantitative analysis of interorganelle lipid transport in live cells. More importantly, with live-cell imaging, we obtained direct evidence that the autophagosomal membrane originates from the endoplasmic reticulum. This method is simple and robust and is thus powerful for real-time tracing of interorganelle lipid trafficking.

Abstract
The long-term stability of affinity-based protein labeling probes is crucial to obtain reproducible protein labeling results. However, highly stable probes generally suffer from low protein labeling efficiency and pose significant challenges when labeling low abundance native proteins in living cells. In this paper, we report that protein labeling probes based on an ortho-difluorophenyl ester reactive module exhibit long-term stability in DMSO stock solution and aqueous buffer, yet they can undergo rapid and selective labeling of native proteins. This novel electrophile can be customized with a wide range of different protein ligands and is particularly well-suited for the labeling and imaging of transmembrane proteins. With this probe design, the identity and relative levels of basal and hypoxia-induced transmembrane carbonic anhydrases were revealed by live cell imaging and in-gel fluorescence analysis. We believe that the extension of this difluorophenyl ester reactive module would allow for the specific labeling of various endogenous membrane proteins, facilitating in-depth studies of their distribution and functions in biological processes.

Abstract
Abiotic allosterism is most commonly observed in hetero-bimetallic supramolecular complexes and less frequently in homo-bimetallic complexes. The use of hemilabile ligands with high synthetic complexity enables the catalytic center by the addition or removal of allosteric effectors and simplicity is unusually seen in these systems. Here we describe a simpler approach to achieve kinetic regulation by the use of dimeric Schiff base copper complexes connected by a chlorido ligand bridge. The chlorido ligand acts as a weak link between monomers, generating homo-bimetallic self-aggregating supramolecular complexes that generate monomeric species in different reaction rates depending on the solvent and on the radical moiety of the ligand. The ligand exchange was observed by electron paramagnetic resonance (EPR) and conductivity measurements, indicating that complexes with ligands bearing methoxyl (CuIIL2) and ethoxyl (CuIIL5) radicals were more prone to form dimeric complexes in comparison to ligands bearing hydrogen (CuIIL1), methyl (CuIIL3), or t-butyl (CuIIL4) radicals. The equilibrium between dimer and monomer afforded different reactivities of the complexes in acetonitrile/water and methanol/water mixtures toward urea hydrolysis as a model reaction. It was evident that the dimeric species were inactive and that by increasing the water concentration in the reaction medium, the dimeric structures dissociated to form the active monomeric structures. This behavior was more pronounced when methanol/water mixtures were employed due to a slower displacement of the chlorido bridge in this medium than in the acetonitrile/water mixtures, enabling the reaction kinetics to be evaluated. This effect was attributed to the preferential solvation shell by the organic solvents and in essence, an upregulation behavior was observed due to the intrinsic nature of the complexes to form dimeric structures in solution that could be dismantled in the presence of water, indicating their possible use as water-sensors in organic solvents.

Abstract
Investigating functions of membrane-bound receptors provides invaluable information about cellular signaling and physiological events. Recently, chemical genetic methods to design chemical switches on the target proteins have intensely been developed for interrogation of the cellular signaling of individual receptor proteins. We recently reported coordination chemistry-based chemogenetics to allosterically activate two types of neurotransmitter receptors, ionotropic and metabotropic glutamate receptors, in living cells. Based on their well-studied structure-activity relationships, we semi-rationally incorporated two His mutations into glutamate receptors near ligand binding pockets as an allosteric site. The engineered glutamate receptors could be allosterically activated upon treatment of Pd(bpy) complex (bpy: 2,2'-bipyridine) through stabilization of the activated conformation in mammalian cells and cultured neurons. Here, we describe the detailed protocol of our approach including the receptor design and activation of the His-engineered receptors and the downstream of the signal transduction cascade in living cells.

Abstract
Cell-based therapy is a promising approach to restoring lost functions to compromised organs. However, the issue of inefficient cell engraftment remains to be resolved. Herein, we take a chemical approach to facilitate cell engraftment by using self-assembling molecules which modify two cellular traits: cell survival and invasiveness. In this system, the self-assembling molecule induces syndecan-4 clusters on the cellular surface, leading to enhanced cell viability. Further integration with Halo-tag technology provided this self-assembly structure with matrix metalloproteinase-2 to functionalize cells with cell-invasion activity. In vivo experiments showed that the pretreated cells were able to survive injection and then penetrate and engraft into the host tissue, demonstrating that the system enhances cell engraftment. Therefore, cell-surface modification via an alliance between self-assembling molecules and ligation technologies may prove to be a promising method for cell engraftment.

Abstract
Investigating individual G-protein-coupled receptors (GPCRs) involved in various signaling cascades can unlock a myriad of invaluable physiological findings. One of the promising strategies for addressing the activity of each subtype of receptor is to design chemical turn-on switches on the target receptors. However, valid methods to selectively control class A GPCRs, the largest receptor family encoded in the human genome, remain limited. Here, we describe a novel approach to chemogenetically manipulate activity of engineered class A GPCRs carrying a His4 tag, using metal complex-agonist conjugates (MACs). This manipulation is termed coordination tethering. With the assistance of coordination bonds, MACs showed 10-100-fold lower EC50 values in the engineered receptors, compared with wild-type receptors. Such coordination tethering enabled selective activation of β2-adrenoceptors and muscarinic acetylcholine receptors, without loss of natural receptor responses, in living mammalian cells, including primary cultured astrocytes. Our generalized, modular chemogenetic approach should facilitate more precise control and deeper understanding of individual GPCR signaling pathways in living systems.

Abstract
G-protein-coupled receptors (GPCRs) play critical roles in regulating brain function. Recent advances have greatly expanded our understanding of these receptors as complex signaling machines that can adopt numerous conformations and modulate multiple downstream signaling pathways. While agonists and antagonists have traditionally been pursued to target GPCRs, allosteric modulators provide several mechanistic advantages, including the ability to distinguish between closely related receptor subtypes. Recently, the discovery of allosteric ligands that confer bias and modulate some, but not all, of a given receptor's downstream signaling pathways can provide pharmacological modulation of brain circuitry with remarkable precision. In addition, allosteric modulators with unprecedented specificity have been developed that can differentiate between subpopulations of a given receptor subtype based on the receptor's dimerization state. These advances are not only providing insight into the biological roles of specific receptor populations, but hold great promise for treating numerous CNS disorders.
