Function (UniProt annotation)
Inositol 4-phosphatase which mainly acts onphosphatidylinositol 4-phosphate May be functionally linked toOCRL, which converts phosphatidylinositol 4,5-bisphosphate tophosphatidylinositol, for a sequential dephosphorylation ofphosphatidylinositol 4,5-bisphosphate at the 5 and 4 position ofinositol, thus playing an important role in the endocyticrecycling (PubMed:25869669) Regulator of TF:TFRC and integrinsrecycling pathway, is also involved in cell migration mechanisms(PubMed:25869669) Modulates AKT/GSK3B pathway by decreasing AKTand GSK3B phosphorylation (PubMed:17322895) Negatively regulatesSTAT3 signaling pathway through inhibition of STAT3phosphorylation and translocation to the nucleus(PubMed:25476455) Functionally important modulator of cardiacmyocyte size and of the cardiac response to stress (Bysimilarity) May play a role as negative regulator of axonregeneration after central nervous system injuries (Bysimilarity)
At the early endosome membrane, phosphatidylinositol 3,5-bisphosphate (PI(3,5)P2) is generated in two steps from phosphatidylinositol 3,4-bisphosphate PI(3,4)P2 by the action of various kinases and phosphatases (Sbrissa et al. 2007, Sbrissa et al. 2008, Cao et al. 2007, Cao et al. 2008, Arcaro et al. 2000, Kim et al. 2002)
