Species: Homo sapiens
About GJB2
This gene has 2 transcripts (splice variants), 290 orthologues, 20 paralogues and is associated with 22 phenotypes. Biased expression in esophagus (RPKM 338.5) and skin (RPKM 18.9).
Summary
This gene encodes a member of the Gap Junction Protein family. The gap junctions were first characterized by electron microscopy as regionally specialized structures on plasma membranes of contacting adherent cells. These structures were shown to consist of cell-to-cell channels that facilitate the transfer of ions and small molecules between cells. The gap junction proteins, also known as connexins, purified from fractions of enriched gap junctions from different tissues differ. 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 are responsible for as much as 50% of pre-lingual, recessive deafness. [provided by RefSeq, Oct 2008]
