Anti-Protein Kinase C, epsilon (PKCe)

PKCe is a member of the novel protein kinase C family of serine/threonine kinases. Its activity is calcium-independent and phospholipid-dependent and is expressed at low levels in normal tissue except the brain, where expression is higher. PKCe expression appears to be induced by interferon-a and its over-expression may play a role in tumorigenesis. PKCe, through its regulatory domain, can induce immature neurite-like processes via a mechanism that appears to be of importance for neurite outgrowth during neuronal differentiation., Protein kinase C (PKC) mediates a wide range of biological responses, including serotonin release from platelets, histamine release from mast cells, glycogen hydrolysis in the liver, fat synthesis by adipocytes, and many others. PKC was described as a serine/threonine protein kinase activated by the presence of Ca2+, phospholipids, and sn-1,2 diacylglycerol (Nishizuka, 1986). In humans, PKC is found as 11 different isoforms which vary in amino acid sequence, structure, subcellular localization, tissue distribution, substrate specificity, and responses to extracellular signals., The PKC isoforms can be grouped based on their requirements for Ca2+ and phospholipids for activation. The isoforms of group 1 include PKCa, PKCbI, PKCbII, and PKCg. Group 1 isoforms require both Ca2+ and phospholipids for activation. The isoforms of group 2 include PKCo, PKCe, PKCh, and PKCq. Group 2 isoforms require phospholipid for activation, but do not require the presence of Ca2+. The isoforms of group 3 include PKCz, PKCm, and PKCi. Group 3 isoforms are not activated by the presence of diacylglycerol or by phorbol esters such as phorbol myristate acetate. Applications: Suitable for use in ELISA and Western Blot.
