Kcnj12 Gene Summary [Rat]

Enables PDZ domain binding activity. Predicted to be involved in potassium ion import across plasma membrane; protein homotetramerization; and regulation of monoatomic ion transmembrane transport. Located in T-tubule; dendrite; and neuronal cell body. Orthologous to several human genes including KCNJ12 (potassium inwardly rectifying channel subfamily J member 12).

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 Kcnj12 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
