Sstr2 Gene Summary [Rat]
Enables PDZ domain binding activity and somatostatin receptor activity. Involved in several processes, including brain development; cellular response to estradiol stimulus; and peristalsis. Predicted to be located in cytosol; membrane; and nucleoplasm. Predicted to be part of G protein-coupled receptor heterodimeric complex. Predicted to be active in neuron projection and plasma membrane. Orthologous to human SSTR2 (somatostatin receptor 2). [provided by Alliance of Genome Resources, Jul 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 rat Sstr2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
