Gap junction protein, alpha 7, 45kDa, also known as GJA7, is a human gene.^[1]

This gene is a member of the connexin gene family. The encoded protein is a component of gap junctions, which are composed of arrays of intercellular channels that provide a route for the diffusion of low molecular weight materials from cell to cell. Alternatively spliced transcript variants encoding the same isoform have been described.^[1]
