GJB1 - gap junction protein beta 1 Gene
Also Known as CMTX; CX32; CMTX1
Species: Homo sapiens
About GJB1
This gene has 11 transcripts (splice variants), 265 orthologues, 20 paralogues and is associated with 3 phenotypes. Biased expression in liver (RPKM 81.6), kidney (RPKM 24.7) and 10 other tissues.
Summary
This gene encodes a member of the Gap Junction Protein family. The gap junction proteins are membrane-spanning proteins that assemble to form gap junction channels that facilitate the transfer of ions and small molecules between cells. According to sequence similarities at the nucleotide and amino acid levels, the gap junction proteins are divided into two categories, alpha and beta. Mutations in this gene cause X-linked Charcot-Marie-Tooth disease, an inherited peripheral neuropathy. Alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Oct 2008]
