Abstract
Generation of amyloid-β (Aβ) peptides through the proteolytic processing of the amyloid precursor protein (APP) is a pathogenic event in Alzheimer's disease (AD). APP is a transmembrane protein and endocytosis of APP mediated by the YENPTY motif is a key step in Aβ generation. Mints, a family of cytosolic adaptor proteins, directly bind to the YENPTY motif of APP and facilitate APP trafficking and processing. Here, we generated and examined two Mint1 mutants, Tyr633Ala of Mint1 (Mint1Y633A) that enhanced APP binding, and Tyr549Ala and Phe610Ala mutant (Mint1Y549A/F610A), that reduced APP binding. We investigated how perturbing the APP-Mint1 interaction through these Mint1 mutants alter APP and Mint1 cellular dynamics and Mint1's interaction with its other binding partners. We found that Mint1Y633A increased binding affinity specifically for APP and presenilin1 (catalytic subunit of γ-secretase), that subsequently enhanced APP endocytosis in primary murine neurons. Conversely, Mint1Y549A/F610A exhibited reduced APP affinity and Aβ secretion. The effect of Mint1Y549A/F610A on Aβ release was greater compared to knocking down all three Mint proteins supporting the APP-Mint1 interaction is a critical factor in Aβ production. Altogether, this study highlights the potential of targeting the APP-Mint1 interaction as a therapeutic strategy for AD.

Abstract
![]()
Intrinsically disordered
regions in proteins often function as
binding motifs in protein–protein interactions. The mechanistic
aspects and molecular details of such coupled binding and folding
reactions, which involve formation of multiple noncovalent bonds,
have been broadly studied theoretically, but experimental data are
scarce. Here, using a combination of protein semisynthesis to incorporate
phosphorylated amino acids, backbone amide-to-ester modifications,
side chain substitutions, and binding kinetics, we examined the interaction
between the intrinsically disordered motif of amyloid precursor protein
(APP) and the phosphotyrosine binding (PTB) domain of Mint2. We show
that the interaction is regulated by a self-inhibitory segment of
the PTB domain previously termed ARM. The helical ARM linker decreases
the association rate constant 30-fold through a fast pre-equilibrium
between an open and a closed state. Extensive side chain substitutions
combined with kinetic experiments demonstrate that the rate-limiting
transition state for the binding reaction is governed by native and
non-native hydrophobic interactions and hydrogen bonds. Hydrophobic
interactions were found to be particularly important during crossing
of the transition state barrier. Furthermore, linear free energy relationships
show that the overall coupled binding and folding reaction involves
cooperative formation of interactions with roughly 30% native contacts
formed at the transition state. Our data support an emerging picture
of coupled binding and folding reactions following overall chemical
principles similar to those of folding of globular protein domains
but with greater malleability of ground and transition states.

Abstract
Alzheimer's disease (AD) is a progressive neurodegenerative disorder that represents the most common cause of dementia in the United States. Although the link between alcohol use and AD has been studied, preclinical research has potential to elucidate neurobiological mechanisms that underlie this interaction. This study was designed to test the hypothesis that nondependent alcohol drinking exacerbates the onset and magnitude of AD-like neural and behavioral pathology. We first evaluated the impact of voluntary 24-h, two-bottle choice home-cage alcohol drinking on the prefrontal cortex and amygdala neuroproteome in C57BL/6J mice and found a striking association between alcohol drinking and AD-like pathology. Bioinformatics identified the AD-associated proteins MAPT (Tau), amyloid beta precursor protein (APP), and presenilin-1 (PSEN-1) as the main modulators of alcohol-sensitive protein networks that included AD-related proteins that regulate energy metabolism (ATP5D, HK1, AK1, PGAM1, CKB), cytoskeletal development (BASP1, CAP1, DPYSL2 [CRMP2], ALDOA, TUBA1A, CFL2, ACTG1), cellular/oxidative stress (HSPA5, HSPA8, ENO1, ENO2), and DNA regulation (PURA, YWHAZ). To address the impact of alcohol drinking on AD, studies were conducted using 3xTg-AD mice that express human MAPT, APP, and PSEN-1 transgenes and develop AD-like brain and behavioral pathology. 3xTg-AD and wild-type mice consumed alcohol or saccharin for 4 months. Behavioral tests were administered during a 1-month alcohol-free period. Alcohol intake induced AD-like behavioral pathologies in 3xTg-AD mice including impaired spatial memory in the Morris Water Maze, diminished sensorimotor gating as measured by prepulse inhibition, and exacerbated conditioned fear. Multiplex immunoassay conducted on brain lysates showed that alcohol drinking upregulated primary markers of AD pathology in 3xTg-AD mice: Aβ 42/40 ratio in the lateral entorhinal and prefrontal cortex and total Tau expression in the lateral entorhinal cortex, medial prefrontal cortex, and amygdala at 1-month post alcohol exposure. Immunocytochemistry showed that alcohol use upregulated expression of pTau (Ser199/Ser202) in the hippocampus, which is consistent with late-stage AD. According to the NIA-AA Research Framework, these results suggest that alcohol use is associated with Alzheimer's pathology. Results also showed that alcohol use was associated with a general reduction in Akt/mTOR signaling via several phosphoproteins (IR, IRS1, IGF1R, PTEN, ERK, mTOR, p70S6K, RPS6) in multiple brain regions including hippocampus and entorhinal cortex. Dysregulation of Akt/mTOR phosphoproteins suggests alcohol may target this pathway in AD progression. These results suggest that nondependent alcohol drinking increases the onset and magnitude of AD-like neural and behavioral pathology in 3xTg-AD mice.

Abstract
Protein-protein interactions within protein networks shape the human interactome, which often is promoted by specialized protein interaction modules, such as the postsynaptic density-95 (PSD-95), discs-large, zona occludens 1 (ZO-1) (PDZ) domains. PDZ domains play a role in several cellular functions, from cell-cell communication and polarization, to regulation of protein transport and protein metabolism. PDZ domain proteins are also crucial in the formation and stability of protein complexes, establishing an important bridge between extracellular stimuli detected by transmembrane receptors and intracellular responses. PDZ domains have been suggested as promising drug targets in several diseases, ranging from neurological and oncological disorders to viral infections. In this review, the authors describe structural and genetic aspects of PDZ-containing proteins and discuss the current status of the development of small-molecule and peptide modulators of PDZ domains. An overview of potential new therapeutic interventions in PDZ-mediated protein networks is also provided.

Abstract
X11/Mint 1 and X11-like (X11L)/Mint 2 are neuronal adaptor protein to regulate trafficking and/or localization of various membrane proteins. By analyzing the localization of neuronal membrane proteins in X11-, X11L-, and X11/X11L doubly deficient mice with membrane fractionation procedures, we found that deficient of X11 and X11L decreased the level of glutamate receptors in non-PSD fraction. This finding suggests that X11 and X11L regulate the glutamate receptor micro-localization to the extrasynaptic region. In vitro coimmunoprecipitation studies of NMDA receptors lacking various cytoplasmic regions with X11 and X11L proteins harboring domain deletion suggest that extrasynaptic localization of NMDA receptor may be as a result of the multiple interactions of the receptor subunits with X11 and X11L regulated by protein phosphorylation, while that of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor subunits is not dependent on the binding with X11 and X11L proteins. Because the loss of X11 and X11L tends to impair the exocytosis, but not endocytosis, of glutamate receptors, NMDA receptors are likely to be supplied to the extrasynaptic plasma membrane with a way distinct from the mechanism regulating the localization of NMDA receptors into synaptic membrane region. Reduced localization of NMDA receptor into the extrasynaptic region increased slightly the phosphorylation level of cAMP responsible element binding protein in brain of X11/X11L doubly deficient mice compare to wild-type mice, suggesting a possible role of X11 and X11L in the regulation of signal transduction pathway through extrasynaptic glutamate receptors.
