Pip4k2b - phosphatidylinositol-5-phosphate 4-kinase type 2 beta

Predicted to enable 1-phosphatidylinositol-4-phosphate 5-kinase activity; protein homodimerization activity; and purine ribonucleoside triphosphate binding activity. Predicted to be involved in several processes, including 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate biosynthetic process; autophagosome-lysosome fusion; and negative regulation of 1-phosphatidylinositol-4-phosphate 5-kinase activity. Predicted to act upstream of or within phosphatidylinositol metabolic process. Predicted to be located in autophagosome; nucleoplasm; and plasma membrane. Orthologous to human PIP4K2B (phosphatidylinositol-5-phosphate 4-kinase type 2 beta). [provided by Alliance of Genome Resources, Apr 2022]
