GJB6 - gap junction protein beta 6 Gene
Also Known as ED2; EDH; HED; CX30; HED2; DFNA3; ECTD2; DFNA3B; DFNB1B
Species: Homo sapiens
About GJB6
This gene has 14 transcripts (splice variants), 284 orthologues, 20 paralogues and is associated with 12 phenotypes. Biased expression in esophagus (RPKM 49.4), bone marrow (RPKM 18.1) and 3 other tissues.
Summary
Gap junctions allow the transport of ions and metabolites between the cytoplasm of adjacent cells. They are formed by two hemichannels, made up of six connexin proteins assembled in groups. Each connexin protein has four transmembrane segments, two extracellular loops, a cytoplasmic loop formed between the two inner transmembrane segments, and the N- and C-terminus both being in the cytoplasm. The specificity of the gap junction is determined by which connexin proteins comprise the hemichannel. In the past, connexin protein names were based on their molecular weight, however the new nomenclature uses sequential numbers based on which form (alpha or beta) of the gap junction is present. This gene encodes one of the connexin proteins. Mutations in this gene have been found in some forms of deafness and in some families with hidrotic ectodermal dysplasia.
