Shank1 Gene Summary [Mouse]
Enables ionotropic glutamate receptor binding activity and synaptic receptor adaptor activity. A structural constituent of postsynaptic density. Involved in several processes, including dendritic spine morphogenesis; learning or memory; and regulation of signal transduction. Acts upstream of or within negative regulation of actin filament bundle assembly. Located in dendritic spine; excitatory synapse; and plasma membrane. Is active in Schaffer collateral - CA1 synapse; glutamatergic synapse; and postsynaptic density. Colocalizes with postsynaptic membrane. Is expressed in cerebral cortex; frontal cortex; and neocortex region. Orthologous to human SHANK1 (SH3 and multiple ankyrin repeat domains 1). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Shank1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
