Summaries for GJB7 Gene

Entrez Gene Summary for GJB7 Gene

  • Connexins, such as GJB7, are involved in the formation of gap junctions, intercellular conduits that directly connect the cytoplasms of contacting cells. Each gap junction channel is formed by docking of 2 hemichannels, each of which contains 6 connexin subunits (Sohl et al., 2003 [PubMed 12881038]).[supplied by OMIM, Mar 2008]

GeneCards Summary for GJB7 Gene

GJB7 (Gap Junction Protein, Beta 7, 25kDa) is a Protein Coding gene. Among its related pathways are Clathrin derived vesicle budding and Signaling in Gap Junctions. An important paralog of this gene is GJB3.

UniProtKB/Swiss-Prot for GJB7 Gene

  • One gap junction consists of a cluster of closely packed pairs of transmembrane channels, the connexons, through which materials of low MW diffuse from one cell to a neighboring cell.

Tocris Summary for GJB7 Gene

  • Gap channels (also known as gap junctions) are specalized cell-cell contacts between almost all eukaryotic cells that provide direct intracellular communication. Generally, gap channels allow the passive diffusion of molecules up to 1 kDa which includes nutrients, small metabolites (e.g. glucose), ions (K+, Ca2+) and second messengers (IP3, cAMP and cGMP). Gap channels allow electrical and biochemical coupling between cells and in excitable tissues, such as neurons and the heart, enables the generation of synchronized and rapid responses. Structurally, gap channels are composed of two hemichannels called 'connexons', which themselves are formed from six connexin molecules. Homo- and heteromeric combinations are seen, which exhibit distinct permeability, selectivity and functional properties. Pannexins are related to connexins and can also form gap junctions. However, their expression is limited to the brain. Furthermore, in nonchordate animals a family of proteins called innexins form these channels. Gap channels are regulated through post-translational modifications of the C'-terminal cytoplasmic tail and phosphorylation modulates assembly and their physiological properties. They are continuously synthesized and degraded, allowing tissues to rapidly adapt to changing environmental conditions. Connexins play a key role in many physiological processes including cardiac and smooth muscle contraction, regulation of neuronal excitability, epithelial electrolyte transport and keratinocyte differentiation. Mutations in connexin genes are associated with human diseases including sensorineural deafness, a variety of skin disorders, peripheral neuropathy and cardiovascular disease.
