Cd320 Gene Summary [Mouse]
Enables cargo receptor activity. Involved in cobalamin transport. Acts upstream of or within regulation of vitamin metabolic process. Is active in plasma membrane. Is expressed in several structures, including gonad; heart; immune system; liver; and metanephros. Used to study methylmalonic acidemia due to transcobalamin receptor defect. Human ortholog(s) of this gene implicated in methylmalonic acidemia due to transcobalamin receptor defect. Orthologous to human CD320 (CD320 molecule).

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 Cd320 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
