Inpp5b Gene Summary [Rat]

Predicted to enable inositol-1,4,5-trisphosphate 5-phosphatase activity and phosphatidylinositol-4,5-bisphosphate 5-phosphatase activity. Predicted to be involved in phosphatidylinositol dephosphorylation. Predicted to act upstream of or within several processes, including flagellated sperm motility; in utero embryonic development; and regulation of protein processing. Predicted to be located in early endosome membrane and phagocytic vesicle membrane. Predicted to be active in cytosol; membrane; and neuron projection. Orthologous to human INPP5B (inositol polyphosphate-5-phosphatase B). [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 Inpp5b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
