Summaries for GJC3 Gene

Entrez Gene Summary for GJC3 Gene

  • This gene encodes a gap junction protein. The encoded protein, also known as a connexin, plays a role in formation of gap junctions, which provide direct connections between neighboring cells. Mutations in this gene have been reported to be associated with nonsyndromic hearing loss.[provided by RefSeq, Feb 2010]

GeneCards Summary for GJC3 Gene

GJC3 (Gap Junction Protein Gamma 3) is a Protein Coding gene. Diseases associated with GJC3 include Mednik Syndrome. GO annotations related to this gene include protein homodimerization activity. An important paralog of this gene is GJB3.

UniProtKB/Swiss-Prot for GJC3 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 GJC3 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).
