Phosphatidylinositol 4-Phosphate 5-Kinase Type-1 Alpha

**Semantic type:** Amino Acid, Peptide, or Protein|Enzyme

**Definition:** Phosphatidylinositol 4-phosphate 5-kinase type-1 alpha (562 aa, ~63 kDa) is encoded by the human PIP5K1A gene. This protein is involved in the phosphorylation of phosphatidylinositol 4-phosphate (PtdIns4P/PI4P) to form phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2/PIP2).
