Arl8b Gene Summary [Mouse]
Predicted to enable G protein activity; guanyl ribonucleotide binding activity; and tubulin binding activity. Involved in several processes, including antigen processing and presentation of polysaccharide antigen via MHC class II; late endosome to lysosome transport; and viral exocytosis. Acts upstream of or within endosomal transport. Located in axon; lysosome; and synapse. Is expressed in several structures, including alimentary system; brain; extraembryonic component; limb; and sensory organ. Orthologous to human ARL8B (ARF like GTPase 8B).

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 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.
