Ms4a1 Gene Summary [Mouse]
Predicted to enable epidermal growth factor receptor binding activity; identical protein binding activity; and immunoglobulin binding activity. Involved in positive regulation of calcium ion import across plasma membrane. Acts upstream of or within response to bacterium. Located in external side of plasma membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and liver and biliary system. Human ortholog(s) of this gene implicated in common variable immunodeficiency 5. Orthologous to human MS4A1 (membrane spanning 4-domains A1). [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 Ms4a1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
