Snx18 Gene Summary [Rat]
Predicted to enable phosphatidylinositol-4,5-bisphosphate binding activity. Predicted to be involved in several processes, including cytoskeleton-dependent cytokinesis; plasma membrane tubulation; and positive regulation of autophagosome assembly. Predicted to be located in several cellular components, including cytoplasmic side of plasma membrane; extracellular exosome; and growth cone. Predicted to be active in plasma membrane and recycling endosome membrane. Orthologous to human SNX18 (sorting nexin 18). [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 rat Snx18 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
