Phospho-PKCa (Thr497) (Clone: F1) rabbit mAb

PKC alpha is a calcium-dependent isozyme of the PKC family that phosphorylates serine/threonine residues in apoptosis and cellular proliferation and differentiation pathways, including the MAPK cascade. PKC alpha directly phosphorylated Raf-1, inducing survival genes. An increase in PKC alpha is associated with multi-drug resistance in cancer cell lines, and increased expression in breast cancers is noted as causing a particularly malignant phenotype. Thus PKC alpha has been the target of novel cancer therapeutics, with some promising developments in microRNA inhibitors. PKC alpha is itself phosphorylated by mTOR. PKC alpha also plays an important role in water regulator and solute absorption in the cell, where it regulates aquaporin 2 by initiating AQP2 ubiquination and lysosomal degradation.
