Protein: SH3 and multiple ankyrin repeat domains protein 1 (Shank1) (GKAP/SAPAP-interacting protein) (SPANK-1) (Somatostatin receptor-interacting protein) (SSTR-interacting protein) (SSTRIP) (Synamon) (Q9WV48)
Organism: Rattus norvegicus (Rat)
Function: 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.
Subcellular location: Cytoplasm {ECO:0000269|PubMed:10433269}. Synapse {ECO:0000269|PubMed:10433269}. Postsynaptic density {ECO:0000269|PubMed:10433269}. Note=Colocalizes with alpha-latrotoxin receptor 1.
