Rab27b Gene Summary [Mouse]

Enables GTP binding activity and GTPase activity. Predicted to be involved in several processes, including anterograde axonal protein transport; multivesicular body sorting pathway; and synaptic vesicle endocytosis. Located in Golgi apparatus. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Used to study platelet storage pool deficiency. Orthologous to human RAB27B (RAB27B, member RAS oncogene family). [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 Rab27b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
