Rabbit anti Human Connexin 43 antibody recognizes rat connexin43, a ~43 kDa member of the alpha-type (group II) subfamily of the connexins. It is a component of gap junctions, the small channels linking the cytoplasm of adjacent cells and enabling signalling through the transfer of ions and metabolites. Phosphorylation of Connexin 43 at serine 368 regulates the permeability of the gap junction. Connexin 43 is the major protein of gap junctions in the heart, essential to synchronised contractions. It is also crucial in embryonic development and is associated with epilepsy.
