Function
Acts as a phosphoinositide 5- and phosphoinositide 6-phosphatase and regulates cellular levels of inositol pentakisphosphate (InsP5) and inositol hexakisphosphate (InsP6) (PubMed:26628373). Also acts as a 2,3-bisphosphoglycerate 3-phosphatase, by mediating the dephosphorylation of 2,3-bisphosphoglycerate (2,3-BPG) to produce phospho-D-glycerate without formation of 3-phosphoglycerate (By similarity). Has a role in embryonic tracheal development where it localizes to the leading edge of actively migrating branches (PubMed:26628373). In these leading cells, enhances formation and/or maintenance of filopodia which may drive branch migration and elongation by cell-cell intercalation (PubMed:26628373). The function in tracheal morphogenesis is dependent on its inositol polyphosphate phosphatase activity (PubMed:26628373).
