Domain

PIKfyve, DEP domain (IPR037378)

Short name: PIKfyve_DEP

Domain relationships

  • DEP domain (IPR000591)
    • PIKfyve, DEP domain (IPR037378)

Description

PIKfyve catalyzes the phosphorylation of phosphatidylinositol 3-phosphate on the fifth hydroxyl of the myo-inositol ring, to form phosphatidylinositol 3,5-bisphosphate [PMID: 17556371]. It is part of the PI(3,5)P2 regulatory complex that regulates both the synthesis and turnover of phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2) [PMID: 19840946]. PIKfyve contains N-terminal Fyve finger and DEP domains, a central chaperonin-like domain and a C-terminal PIPK (phosphatidylinositol phosphate kinase) domain.
