Arl8b Gene Summary [Rat]
Predicted to enable G protein activity; guanyl ribonucleotide binding activity; and tubulin binding activity. Predicted to be involved in several processes, including antigen processing and presentation following phagocytosis; cytosolic transport; and vesicle fusion. Predicted to act upstream of or within endosomal transport. Predicted to be located in several cellular components, including cytolytic granule membrane; midbody; and spindle midzone. Predicted to be active in early endosome membrane and lysosomal membrane. Orthologous to human ARL8B (ARF like GTPase 8B). [provided by Alliance of Genome Resources, Apr 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 rat Arl8b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
