Applications Key:  W=Western Blotting  F=Flow Cytometry
Reactivity Key:  H=Human  M=Mouse  R=Rat  Mk=Monkey
Species cross-reactivity is determined by Western blot.

Specificity / Sensitivity

PKD/PKCmu Antibody detects endogenous levels of total PKD1/PKCmu protein. It does does not cross-react with other PKC isoforms.

Source / Purification

Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH-coupled) corresponding to residues surrounding Ser916 of mouse PKD. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from NIH/3T3 cells, untreated, PDGF-treated (50 ng/ml) or TPA-treated (0.2 µM), using PKD/PKCmu Antibody.

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of NIH/3T3 cells, using PKD/PKCmu Antibody (blue) compared to a nonspecific negative control antibody (red).

Background

Activation of PKC is one of the earliest events in a cascade leading to a variety of cellular responses such as secretion, gene expression, proliferation and muscle contraction (1,2). Protein kinase D (PKD), also called PKCμ, is a serine/threonine kinase whose activation is dependent on the phosphorylation of two activation loop sites, Ser744 and Ser748, via a PKC-dependent signaling pathway (3-5). In addition to the two activation loop sites, the carboxy-terminal Ser916 has been identified as an autophosphorylation site for PKD/PKCμ. Phosphorylation at Ser916 correlates with PKD/PKCμ catalytic activity (6).
