'''Crystal Structure of the SH3-HOOK-GK Fragment of PSD-95'''<br />

==Overview==

PSD-95/SAP90 is a member of the MAGUK superfamily. In excitatory synapses, PSD-95 clusters receptors and ion channels at specific sites in the, postsynaptic membrane and organizes downstream signaling and cytoskeletal, molecules. We have determined the crystal structures of the apo and, GMP-bound forms to 2.3 and 2.0 A resolutions, respectively, of a fragment, containing the SH3, HOOK, and guanylate kinase (GK) domains of PSD-95. We, observe an intramolecular interaction between the SH3 and GK domains, involving the formation of a beta sheet including residues N- and, C-terminal to the GK domain. Based on amino acid conservation and, mutational data available in the literature, we propose that this, intramolecular interaction is a common feature among MAGUK proteins.
