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) is a Protein Coding gene. Among its related pathways are Gap junction trafficking and Vesicle-mediated transport. 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 (gap junctions) are specialized cell-cell contacts that provide direct intracellular communication. They allow passive diffusion of molecules up to 1 kDa, including nutrients, metabolites (glucose), ions (K+, Ca2+) and second messengers (IP3, cAMP).
