Atp2b4 Gene Summary [Mouse]
Enables scaffold protein binding activity and sodium channel regulator activity. Involved in several processes, including negative regulation of blood vessel endothelial cell migration; negative regulation of calcineurin-NFAT signaling cascade; and negative regulation of cardiac muscle hypertrophy in response to stress. Located in T-tubule and sperm flagellum. Part of protein-containing complex. Is expressed in several structures, including bladder; heart; intestine wall; liver; and nervous system. Orthologous to human ATP2B4 (ATPase plasma membrane Ca2+ transporting 4). [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 mouse Atp2b4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
