Ms4a1 Gene Summary [Rat]

Enables epidermal growth factor receptor binding activity. Predicted to be involved in several processes, including B cell receptor signaling pathway; calcium ion transport; and positive regulation of calcium ion import across plasma membrane. Predicted to act upstream of or within response to bacterium. Predicted to be located in cell surface; nucleoplasm; and plasma membrane raft. Predicted to be active in external side of plasma membrane. Biomarker of glomerulonephritis. 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 rat 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.
