IUBMB Comments

These enzymes can also remove the 5-phosphate from Ins(1,4,5)P3 and/or Ins(1,3,4,5)P4. They are a diverse family of enzymes, with differing abilities to catalyse two or more of the four reactions listed. They are thought to use inositol lipids rather than inositol phosphates as substrates in vivo. All of them can use either or both of PtdIns(4,5)P2 and PtdIns(3,4,5)P3 as substrates; this is the main property that distinguishes them from EC 3.1.3.56, inositol-polyphosphate 5-phosphatase.

The expected taxonomic range for this enzyme is: Eukaryota, Bacteria

Synonyms
ship2, ship1, ocrl1, synaptojanin, inpp5e, synj1, phosphoinositide phosphatase, inositol polyphosphate 5-phosphatase, inositol 5-phosphatase, ci-vsp, more
