Gephyrin is the central scaffolding protein for inhibitory neurotransmitter receptors in the brain. Here we describe the development of dimeric peptides that inhibit the interaction between gephyrin and these receptors, a process which is fundamental to numerous synaptic functions and diseases of the brain. We first identified receptor-derived minimal(More)
Relaxin-3 and its endogenous receptor RXFP3 are involved in fundamental neurological signalling pathways, such as learning and memory, stress, feeding and addictive behaviour. Consequently, this signalling system has emerged as an attractive drug target. Development of leads targeting RXFP3 relies on assays for screening and ligand optimization. Here, we(More)
PDZ domains in general, and those of PSD-95 in particular, are emerging as promising drug targets for diseases such as ischemic stroke. We have previously shown that dimeric ligands that simultaneously target PDZ1 and PDZ2 of PSD-95 are highly potent inhibitors of PSD-95. However, PSD-95 and the related MAGUK proteins contain three consecutive PDZ domains,(More)
Salt-bridge interactions between acidic and basic amino acids contribute to the structural stability of proteins and to protein–protein interactions. A conserved salt-bridge is a canonical feature of the α-defensin antimicrobial peptide family, but the role of this common structural element has not been fully elucidated. We have investigated mouse Paneth(More)
PDZ domains are ubiquitous small protein domains that are mediators of numerous protein-protein interactions, and play a pivotal role in protein trafficking, synaptic transmission, and the assembly of signaling-transduction complexes. In recent years, PDZ domains have emerged as novel and exciting drug targets for diseases (in the brain in particular), so(More)
