Myo5b Gene Summary [Mouse]
Predicted to enable several functions, including ATP hydrolysis activity; ionotropic glutamate receptor binding activity; and small GTPase binding activity. Involved in modulation of chemical synaptic transmission. Acts upstream of or within protein transmembrane transport. Located in brush border. Is active in Schaffer collateral - CA1 synapse. Is expressed in central nervous system; genitourinary system; gut; heart; and skeletal muscle. Used to study microvillus inclusion disease. Human ortholog(s) of this gene implicated in microvillus inclusion disease and progressive familial intrahepatic cholestasis. Orthologous to human MYO5B (myosin VB).

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 Myo5b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
