PKCβ Mouse, Unlabeled, Clone: 36, BD

Beschreibung

The Protein Kinase C (PKC) family of homologous serine/threonine protein kinases is involved in a number of processes such as growth, differentiation, and cytokine secretion. At least eleven isozymes have been described. These proteins are products of multiple genes and alternative splicing. PKC consists of a single polypeptide chain containing four conserved regions (C) and five variable regions (V). The N-terminal half containing C1, C2, V1, and V2 constitutes the regulatory domain and interacts with the PKC activators Ca²⁺;, phospholipid, diacylglycerol, or phorbol ester. However, the novel PKC (nPKC) subfamily members ( δ, ε, η, and θ isoforms) and the atypical PKC (aPKC) subfamily members (ζ, ι, and λ isoforms) are Ca²⁺; independent and lack the C2 domain. The aPKC members are unique in that their activity is
independent of diacylglycerols and phorbol esters. They also lack one repeat of the cysteine-rich sequences that are conserved in cPKC and nPKC. The C-terminal region of PKC contains the catalytic domain. The PKC pathway represents a major signal transduction system that is activated following ligand-stimulation of transmembrane receptors by hormones, neurotransmitters and growth factors. PKCβ is highly expressed in brain and hematopoietic cells. Autophosphorylation of PKCβ occurs at the N- and C-terminal regions, as well as within the hinge region. However, only the COOH- terminal autophosphorylation sites are essential for PKCβ's function and subcellular localization. PKCβ is critical for the proliferation of K562 cells, as well as being an important regulator of human melanogenesis.
