General description

Connexin 43 (GJA1) is a member of the connexin gene family and a component of gap junctions. Gap junctions are composed of arrays of intercellular channels and provide a route for the diffusion of materials of low molecular weight from cell to cell. GJA1 is the major protein of gap junctions in the heart, and gap junctions are thought to have a crucial role in the synchronized contraction of the heart and in embryonic development. GJA1 is targeted by several protein kinases that regulate myocardial cell cell coupling. A related intronless GJA1 pseudogene, GJA1P, has been mapped to chromosome 5. Mouse Connexin 43 is a 382 amino acid gap junction protein with a predicted M.W. of ~43 kDa. It is prominently expressed in heart (Kumar, N. and Giula, N., 1996, Cell 84: 381-388).

Mouse Connexin 43 is a 382 amino acid gap junction protein with a predicted M.W. of ~43 kDa. It is prominently expressed in heart (see reviews: Kumar & Giula 1996; White et al. 1995; Evans 1994; Beyer et al. 1990).


Mouse C×43 immunogenic peptide sequence is specific for C×43 and no significant homology is seen with other connexins. The mouse C×43 peptide sequence is 100% homologous with rat and human C×43 (Beyer, E. et al., 1985, JCB 105: 2621).

Recognizes mouse Connexin 43.


Anti-Connexin 43 is made against a 23 amino acid C-terminal peptide sequence within the cytoplasmic domain of mouse C×43 (Beyer, E. and Steinberg, T. ,1991, JBC 266: 7971).

Epitope: C-term/cytosolic


2-10 µg of a previous lot was used in immunoprecipitation.

A previous lot of this antibody was used at 1:10,000-100,000 dilution using 50 - 100 ng Cx43 control peptide (Catalog number AG636) per well.

Optimal working dilutions must be determined by end user.
