Reaction: PI is phosphorylated to PI4P by PI4KB at the Golgi membrane
- in pathway: Synthesis of PIPs at the Golgi membrane
At the Golgi membrane, activated phosphatidylinositol 4-kinase beta (PI4KB) complexed to ADP-ribosylation factor 1/3 (ARF1/3) phosphorylates phosphatidylinositol (PI) to phosphatidylinositol 4-phosphate (PI4P) (Suzuki et al. 1997).
Reaction - small molecule participants:
ADP [cytosol]
