Pikfyve Gene Summary [Rat]
Predicted to enable phosphatidylinositol kinase activity; protein serine/threonine kinase activity; and zinc ion binding activity. Predicted to be involved in several processes, including antigen processing and presentation of exogenous peptide antigen via MHC class II; phosphatidylinositol metabolic process; and vesicle organization. Predicted to act upstream of or within myelin assembly. Predicted to be located in several cellular components, including cytoplasmic vesicle membrane; membrane raft; and perinuclear region of cytoplasm. Predicted to be active in cytoplasmic vesicle and vesicle membrane. Human ortholog(s) of this gene implicated in Fleck corneal dystrophy. Orthologous to human PIKFYVE (phosphoinositide kinase, FYVE-type zinc finger containing). [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 Pikfyve often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
