Predicted to enable 1-phosphatidylinositol-3-kinase activity; 1-phosphatidylinositol-4-phosphate 3-kinase activity; and lipid kinase activity. Predicted to be involved in cell migration; phosphatidylinositol 3-kinase signaling; and phosphatidylinositol-3-phosphate biosynthetic process. Predicted to act upstream of or within autophagosome organization; cellular response to starvation; and protein kinase B signaling. Predicted to be located in cytosol; endocytic vesicle; and nucleoplasm. Predicted to be part of phosphatidylinositol 3-kinase complex. Predicted to be active in cytoplasm and plasma membrane. Orthologous to human PIK3C2B (phosphatidylinositol-4-phosphate 3-kinase catalytic subunit type 2 beta). [provided by Alliance of Genome Resources, Apr 2022]
