General 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 (Gene ID: 2697) in human. Cx43 is a member of the gap junction family, which is composed of intercellular channels allowing direct cell-to-cell communication between neighboring cells via the exchange of small ions and metabolites. It is a multi-pass membrane protein with three cytoplasmic domains, four transmembrane domains, and two extracellular domains. It is one of the most widely studied gap junction proteins that regulates N-cadherin expression during collective cell migration. It also acts as a negative regulator of bladder capacity by enhancing intercellular electrical and chemical transmission and thereby exsensitizing bladder muscles to cholinergic neural stimuli and causing them to contract. It is also expressed in gap junctions of the cardiac ventricle and plays an essential role in gap junction communication in the ventricles. Cx43 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. Cx43 is phosphorylated at Ser-368 by PKCg (PRKCG) and this phosphorylation is reported to induce disassembly of gap junction plaques and inhibition of gap junction activity and triggers its internalization into small vesicles leading to proteasome-mediated degradation.

Specificity

Clone 2C6 is a mouse monoclonal antibody that detects Connexin 43 phosphorylated on serine 368.

Immunogen

KLH-conjugated linear peptide corresponding to 11 amino acids surrounding phosphoserine 368 from the C-terminal, cytoplasmic domain of human Connexin 43.

Application

Quality Control Testing

Evaluated by Western Blotting in NRK cell lysate.

Western Blotting Analysis (WB): A 1:500 dilution of this antibody detected Connexin 43 phosphorylated on serine 368 in lysates from untreated NRK cells and in NRK cells treated with 12-O-tetradecanoylphorbol-13-acetate (TPA; 25 nM; 40 min).

Tested Applications

Western Blotting Analysis (WB): A representative lot of this antibody detected phospho-Connexin-43 (Ser368) in NRK cells. ( Solan, JL., and Lampe, PD. (2020). Biomolecules. 10(12); 1596).


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