Pip4k2b - phosphatidylinositol-5-phosphate 4-kinase, type II, beta

Predicted to enable 1-phosphatidylinositol-4-phosphate 5-kinase activity; protein homodimerization activity; and purine ribonucleoside triphosphate binding activity. Involved in autophagosome-lysosome fusion and regulation of autophagy. Acts upstream of or within phosphatidylinositol metabolic process. Predicted to be located in autophagosome; nucleoplasm; and plasma membrane. Is expressed in head bone; nervous system; and sensory organ. Orthologous to human PIP4K2B (phosphatidylinositol-5-phosphate 4-kinase type 2 beta). [provided by Alliance of Genome Resources, Apr 2022]
