Rab1a Gene Summary [Rat]
Enables GTP binding activity. Involved in endocytosis and vesicle transport along microtubule. Acts upstream of or within endoplasmic reticulum to Golgi vesicle-mediated transport. Located in several cellular components, including Golgi membrane; early endosome; and neuronal cell body. Is active in presynapse. Orthologous to human RAB1A (RAB1A, member RAS oncogene family).

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 Rab1a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
