GJA5 - gap junction protein alpha 5 Gene
Also Known as CX40; ATFB11
Species: Homo sapiens
About GJA5
This gene has 3 transcripts (splice variants), 257 orthologues, 20 paralogues and is associated with 5 phenotypes. Biased expression in placenta (RPKM 23.7), lung (RPKM 11.2) and 11 other tissues.
Summary
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. Mutations in this gene may be associated with atrial fibrillation. Alternatively spliced transcript variants encoding the same isoform have been described. [provided by RefSeq, Jul 2008]
