Background

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 cardiac gap junction protein, which is 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.

Limitations
