Predicted to enable 1-phosphatidylinositol-4-phosphate 5-kinase activity; 1-phosphatidylinositol-5-phosphate 4-kinase activity; and protein homodimerization activity. Involved in autophagosome-lysosome fusion; megakaryocyte development; and regulation of autophagy. Located in lysosome. Is expressed in several structures, including alimentary system; genitourinary system; liver; nervous system; and nose. Orthologous to human PIP4K2A (phosphatidylinositol-5-phosphate 4-kinase type 2 alpha). [provided by Alliance of Genome Resources, Apr 2022]
