Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

PIP4K2C (E7P3S) Rabbit mAb recognizes endogenous levels of total PIP4K2C protein. This antibody does not cross-react with PIP4K2A or PIP3K2B proteins.

Species Reactivity:

Human, Mouse, Rat

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu321 of human PIP4K2C protein.

Background

Phosphatidylinositol-5-phosphate 4-kinases (PIP4Ks) synthesize phosphatidylinositol-4,5-bisphosphate (PtdIns(4,5)P2), a key precursor in phosphoinositide signaling that directly modulates the activity of signaling proteins and cellular processes. There are two subfamilies of PIP kinases, type I and II, that generate PtdIns(4,5)P2 from distinct substrate pools. PIP4 type I kinases use PtdIns5P as a substrate, whereas PIP5 type II kinases use PtdIns4P (1,2). In mammalian cells, three isoforms of each PIP4K and PIP5K subfamily, encoded by distinct genes, have been characterized (3-7). All PIP kinases are stimulated by phosphatidic acid, extensively regulated by ARF and Rho GTPases, and inhibited by protein kinase A and PI-stimulated autophosphorylation (8).

PIP4K2C, also known as phosphatidylinositol-5-phosphate 4-kinase type-2 gamma (PI5P4Kγ), is a member of the type II PIP kinase family, and is broadly expressed with the highest levels in kidney and brain tissue (9). PIP4K2C can form a homodimer or heterodimer with its two other known family members, PIP4K2A and PIP4K2B (10). PIP4K2C is a regulator of mammalian target of rapamycin complex 1 (mTORC1) signaling, and Pip4k2c KO mice demonstrate enhanced immune responses and develop autoimmunity (11,12).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
