Summaries for GJC1 Gene

Entrez Gene Summary for GJC1 Gene

  • This gene is a member of the connexin gene family. The encoded protein is a component of gap junctions, which are composed of arrays of intercellular channels that provide a route for the diffusion of low molecular weight materials from cell to cell. Alternatively spliced transcript variants encoding the same isoform have been described. [provided by RefSeq, Jul 2008]

GeneCards Summary for GJC1 Gene

GJC1 (Gap Junction Protein Gamma 1) is a Protein Coding gene. Among its related pathways are Transmission across Electrical Synapses and Gap junction trafficking. Gene Ontology (GO) annotations related to this gene include ion channel activity and gap junction channel activity. An important paralog of this gene is GJC2.

UniProtKB/Swiss-Prot for GJC1 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 GJC1 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).
