Connexin43 Antibody (Phospho-Ser368)

Product Specifications

CAS Number

9007-83-4

Gene Aliases

Cx43, Cxnk1

Gene ID

24392

Accession Number

NP_036699.1

Reactivity

Human, Mouse, Rat, Cow, Dog, Guinea Pig, Zebrafish

Immunogen

Phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser368 of rat connexin43.

Target

Gap junctional intercellular communication is thought to play a key role in development and may also be involved in epilepsy (Aronica et al., 2001) . Connexin43 forms gap-junctional channels and regulates the permeability of these gap junctions to small organic molecules. Permeability of connexin43 is known to be regulated by phosphorylation at Ser368 by protein kinase C (Yogo et al., 2002; Bao et al., 2004a) . Phosphorylation of Ser368 by PKC induces a conformational change of connexin43 that results in a decrease in gap junction permeability (Bao et al., 2004b) .
