== Publication Abstract from PubMed == | |||
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 gephyrin-binding peptides that displayed exclusive binding towards native gephyrin from brain lysates. We then designed and synthesized a series of dimeric ligands, which led to a remarkable 1220-fold enhancement of the gephyrin affinity (KD =6.8 nM). In X-ray crystal structures we visualized the simultaneous dimer-to-dimer binding in atomic detail, revealing compound-specific binding modes. Thus, we defined the molecular basis of the affinity-enhancing effect of multivalent gephyrin inhibitors and provide conceptually novel compounds with therapeutic potential, which will allow further elucidation of the gephyrin-receptor interplay. | |||
