12417658-7	2002	The models (1) reveal that alternative splicing of the beta4 N terminus results in dramatic differences in surface charge distribution and (2) localize the proline-rich motif of beta4b to an extended arm structure that flanks what would be the equivalent of a highly modified PSD-95 carboxylate binding loop.	carboxylate	283-294	discs large MAGUK scaffold protein 4	Homo sapiens	276-282	
24477114-4	2014	We observe substantial and differential effects upon amide-to-ester mutation in PDZ2 of postsynaptic density protein 95 and other PDZ domains, suggesting that hydrogen bonding at the carboxylate-binding site contributes to both affinity and selectivity.	carboxylate	183-194	discs large MAGUK scaffold protein 4	Homo sapiens	88-119	
30988255-6	2019	In this work, crystallographic structures of the following have been solved: a truncated form of the third PDZ domain of the neuronal postsynaptic density protein 95 from which alpha3 has been removed, D332P and D332G variants of the protein, and a new crystal form of this domain showing the binding of Asp332 to the carboxylate-binding site of a symmetry-related molecule.	carboxylate	318-329	discs large MAGUK scaffold protein 4	Homo sapiens	134-165
