Phosphatidylinositol 5-Phosphate 4-Kinase Type-2 Alpha

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

**Definition:** Phosphatidylinositol 5-phosphate 4-kinase type-2 alpha (406 aa, ~46 kDa) is encoded by the human PIP4K2A gene. This protein plays a role in the catalysis of phosphorylation of phosphatidylinositol-4-phosphate to form phosphatidylinositol-4,5-biphosphate, the precursor to second messengers of phosphoinositide signal transduction pathways.
