Abstract
Site-selective lysine post-translational modifications such as acetylation, methylation, hydroxylation, and isopeptide formation mediate the precise control of important signaling events in cells with unmistakable accuracy. This unparalleled site selectivity (modification of a single lysine in a particular protein in the proteome) is still a challenge for non-enzymatic protein reactions; the difficulty lies in the differentiation of the lysine ε-amino group from other reactive groups and in the precise pinpointing of one particular lysine ε-amino group out of many other lysine ε-amino groups and the N-terminal amine of the protein that have similar chemical reactivity. Here, we have explored proximal lysine conjugation reactions through peptide-guided fluorodinitrobenzene, isothiocyanate, and phenyl ester reactions and have validated the site-specific targeting of the ε-amino group of one single lysine in natural proteins that contain multiple lysine residues. This precise site selectivity is a result of the proximity-induced reactivity guided by a specific protein-peptide interaction: the binding interaction preorganizes an amine-reactive group in the peptide and one of the lysine side chain ε-amino groups of the protein into close proximity, thereby confining the reactivity to a selected area of the target protein. The binding-guide lysine reactions were first examined on an SH3 domain and then tested on several ubiquitin-like proteins such as SUMO, Atg8 protein family, plant ATG8, and mammalian LC3 proteins that contain at least seven lysine residues on the surface. Exquisite site selectivity was confirmed in all of the proteins tested. A set of amine reactions were tested for their feasibility in the site-selective lysine reaction. Selected amine-reactive groups were optimized, and the reaction sites on the LC3 protein were confirmed by mass spectrometry.

Abstract
Melanoma differentiation-associated gene 9 (MDA-9)/Syntenin is a multidomain PDZ protein and identified as a key oncogene in melanoma initially. This protein contains a unique tandem PDZ domain architecture (PDZ1 and PDZ2 spaced by a 4-amino acid linker), an N-terminal domain (NTD) that is structurally uncharacterized and a short C-terminal domain (CTD). The PDZ1 domain is regarded as the PDZ signaling domain while PDZ2 served as the PDZ superfamily domain. It has various cellular roles by regulating many of major signaling pathways in numerous cancertypes. Through the use of novel drug design methods, such as dimerization and unnatural amino acid substitution of inhibitors in our group, the protein may provide a valuable therapeutic target. The objective of this review is to provide a current perspective on the cancer-specific role of MDA-9/Syntenin in order to explore its potential for cancer drug discovery and cancer therapy.

Abstract
Targeted covalent inhibitors of protein-protein interactions differ from reversible inhibitors in that the former bind and covalently bond the target protein at a specific site of the target. The site specificity is the result of the proximity of two reactive groups at the bound state, for example, one mild electrophile in the inhibitor and a natural cysteine in the target close to the ligand binding site. Only a few pharmaceutically relevant proteins have this structural feature. Grb2, a key adaptor protein in maintaining the ERK activity via binding Sos1 to activated RTKs, is one: the N-terminal SH3 domain of Grb2 (Grb2N-SH3) carries a unique solvent-accessible cysteine Cys32 close to its Sos1-binding site. Here we report the design of a peptide-based antagonist (a reactive peptide) that specifically binds to Grb2N-SH3 and subsequently undergoes a nucleophilic reaction with Cys32 to form a covalent bond thioether, to block Grb2-Sos1 interaction. Through rounds of optimization, we eventually obtained a dimeric reaction reactive peptide that can form a covalent adduct with endogenous Grb2 protein inside the cytosol of SK-BR-3 human breast cancer cells with pronounced inhibitory effect on cell mobility and viability. This work showcases a rational design of Grb2-targeted site-specific covalent inhibitor and its pronounced anticancer effect by targeting Grb2-Sos1 interaction.
