Bcap31 Gene Summary [Mouse]
Enables MHC class I protein binding activity. Involved in spermatogenesis. Acts upstream of or within endoplasmic reticulum to Golgi vesicle-mediated transport; immune response; and protein localization to endoplasmic reticulum exit site. Located in Golgi membrane and plasma membrane. Is expressed in embryo. Human ortholog(s) of this gene implicated in deafness, dystonia, and cerebral hypomyelination and sensorineural hearing loss. Orthologous to human BCAP31 (B cell receptor associated protein 31). [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 Bcap31 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
