Npc2 Gene Summary [Mouse]
Enables cholesterol binding activity. Involved in cholesterol efflux and intracellular cholesterol transport. Acts upstream of or within several processes, including cholesterol storage; sterol metabolic process; and sterol transport. Located in extracellular space. Is active in lysosome. Is expressed in brain; paravertebral ganglion; respiratory system; stomach; and ventral grey horn. Used to study Niemann-Pick disease. Human ortholog(s) of this gene implicated in Niemann-Pick disease and Niemann-Pick disease type C2. Orthologous to human NPC2 (NPC intracellular cholesterol transporter 2).

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 Npc2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
