Predicted to enable phosphotransferase activity, alcohol group as acceptor 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. Human ortholog(s) of this gene implicated in Fleck corneal dystrophy. Orthologous to human PIKFYVE (phosphoinositide kinase, FYVE-type zinc finger containing).
