  1. Phosphatidylinositol 3,5-bisphosphate 5-phosphatase
  2. SAC domain-containing protein 3
Gene Name FIG4
Protein Type Unknown
Biological Properties
General Function Not Available
Specific Function The PI(3,5)P2 regulatory complex regulates both the synthesis and turnover of phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2). In vitro, hydrolyzes all three D5-phosphorylated polyphosphoinositide substrates in the order PtdIns(4,5)P2 > PtdIns(3,5)P2 > PtdIns(3,4,5)P3. Plays a role in the biogenesis of endosome carrier vesicles (ECV) / multivesicular bodies (MVB) transport intermediates from early endosomes.
