General description
PI4K2A or phosphatidylinositol 4-kinase type 2 alpha is involved in the formation of phosphatidylinositolpolyphosphates (PtdInsPs) which are centrally involved in many biologic processes ranging from cell growth and organization of the actin cytoskeleton to endo- and exocytosis. PI4K2A phosphorylates PtdIns at the D-4 position which is an essential step in the biosynthesis of PtdInsPs. PI4K2A is a novel regulator of tumor growth by its action on angiogenesis and HIF-1alpha regulation. PI4K2A generates PtdIns4P-rich domains within the Golgi which regulate targeting of clathrin adaptor AP-1 complexes. PI4K2A is also required for Wnt to regulate LRP6 phosphorylation.

Phosphatidylinositol 4 phosphate [PI(4)P] is essential for secretion in yeast, but its role in mammalian cells is unclear. Current paradigms propose that PI(4)P acts primarily as a precursor to phosphatidylinositol 4,5 bisphosphate (PIP2), an important plasma membrane regulator. We found

The canonical Wnt-beta-catenin signaling pathway is initiated by inducing phosphorylation of one of the Wnt receptors, low-density lipoprotein receptor-related protein 6 (LRP6), at threonine residue 1479 (Thr1479) and serine residue 1490 (Ser1490). By screening a human kinase small interfering RNA
