Immunogen

KLH-conjugated linear peptide corresponding to 20 amino acids from the C-terminal region of human Connexin-43.

Application

Anti-Connexin 43, clone 5H23 ZooMAb, Cat. No. ZRB1179, is a highly specific recombinant rabbit monoclonal antibody that detects Connexin-43 and has been tested for use in Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected Connexin-43 in lysates from mouse and human brain and from human heart tissue.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected Connexin-43 in human heart tissue sections.

Immunocytochemistry Analysis: A 1:1,000 dilution from a representative lot detected Connexin-43 in HUVEC ad A431 cells.

Note: Actual optimal working dilutions must be determined by the end user as specimens and experimental conditions may vary.

Target description

Gap junction alpha-1 protein (UniProt: P17302; also known as Connexin-43, Cx43, Gap junction 43 kDa heart protein) is encoded by the GJA1 (also known as GJAL) (Gene ID: 2697) in human. Connexins assemble as hexamers (connexons) to form gap junctions that allow for the passage of ions and other small molecules between neighboring cells. Gap junctions play an important role in a variety of cellular processes including homeostasis, intercellular metabolic cooperation and synchronization, morphogenesis, cell differentiation, and growth control. Connexins usually have a short half-life, which is a key element of coupling regulation as it allows very dynamic and acute changes in gap junction regulation and gap junctional communication. In cardiomyocytes three types of connexins have been identified: Connexin 40, 43, and 45. Each of these connexins form channels with unique and specific electrophysiological properties. Connexin-43 is a multi-pass membrane protein and is the most ubiquitous connexin with widespread tissue expression pattern. It has been detected in Connexin-43 can be phosphorylated at multiple sites and phosphorylation is shown to regulate the kinetics of its trafficking, assembly, gating and turnover in a cell-cycle-stage specific manner. It is phosphorylated at serine 368 by PRKCG and this phosphorylation induces disassembly of gap junction plaques and inhibition of gap junction activity. Phosphorylation at serines 325, 328, and 330 by CK1 modulates gap junction assembly and phosphorylation at serine 368 by PRKCD can trigger its internalization into small vesicles leading to proteasome-mediated degradation. During myocardial ischemia connexin-43 is shown to become dephosphorylated that allows gap junctions to be opened and convey the propagation of ischemia injury. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
