The function of ENSG00000139144 (PIK3C2G, phosphatidylinositol-4-phosphate 3-kinase catalytic subunit type 2 gamma) is as follows. Generates phosphatidylinositol 3-phosphate (PtdIns3P) and phosphatidylinositol 3,4-bisphosphate (PtdIns(3,4)P2) that act as second messengers (By similarity). May play a role in SDF1A-stimulated chemotaxis (By similarity). {ECO:0000250|UniProtKB:O70167, ECO:0000250|UniProtKB:O70173}.
