DESCRIPTION

Also known as SHAN1_RAT, Shank1. Seems to be an adapter protein in the postsynaptic density (PSD) of excitatory synapses that interconnects receptors of the postsynaptic membrane including NMDA-type and metabotropic glutamate receptors, and the actin-based cytoskeleton. Plays a role in the structural and functional organization of the dendritic spine and synaptic junction. Overexpression promotes maturation of dendritic spines and the enlargement of spine heads via its ability to recruit Homer to postsynaptic sites, and enhances presynaptic function. May homomultimerize via its SAM domain. Interacts with the C-terminus of SSTR2 via the PDZ domain. Interacts with SHARPIN, SPTAN1 and DLGAP1/GKAP. Part of a complex with DLG4/PSD-95 and DLGAP1/GKAP. Interacts with BAIAP2 (By similarity). Interacts with IGSF9. Interacts with HOMER1 and HOMER3 (PubMed:19345194).
