Entrez gene summary

Phosphatidylinositol 4-kinases (PI4Ks) phosphorylate phosphatidylinositol to generate phosphatidylinositol 4-phosphate (PIP), an immediate precursor of several important signaling and scaffolding molecules. PIP itself may also have direct functional and structural roles. PI4K2B is a primarily cytosolic PI4K that is recruited to membranes, where it stimulates phosphatidylinositol 4,5-bisphosphate synthesis (Wei et al., 2002 [PubMed 12324459]).[supplied by OMIM, Jun 2008]

Staining summary

A majority of normal tissues displayed moderate to strong cytoplasmic immunoreactivity, in some cases with a granular pattern. Strongest positivity was observed in glandular epithelia of the gastrointestinal tract and in lymphoid tissues.
