Summaries for GJA5 Gene

Entrez Gene Summary for GJA5 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. Mutations in this gene may be associated with atrial fibrillation. Alternatively spliced transcript variants encoding the same isoform have been described. [provided by RefSeq, Jul 2008]

GeneCards Summary for GJA5 Gene

GJA5 (Gap Junction Protein Alpha 5) is a Protein Coding gene. Diseases associated with GJA5 include atrial fibrillation, familial, 11 and atrial standstill, digenic. Among its related pathways are Antiarrhythmic Pathway, Pharmacodynamics and Signaling in Gap Junctions. GO annotations related to this gene include gap junction channel activity and gap junction hemi-channel activity. An important paralog of this gene is GJC2.

UniProtKB/Swiss-Prot for GJA5 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 GJA5 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).

CXA5_HUMAN
  • Atrial fibrillation, familial, 11 (ATFB11) [MIM:614049]: A familial form of atrial fibrillation, a common sustained cardiac rhythm disturbance. Atrial fibrillation is characterized by disorganized atrial electrical activity and ineffective atrial contraction promoting blood stasis in the atria and reduces ventricular filling. It can result in palpitations, syncope, thromboembolic stroke, and congestive heart failure. {ECO:0000269 PubMed:20650941}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Atrial standstill 1 (ATRST1) [MIM:108770]: A rare arrhythmia characterized by the absence of electrical and mechanical activity in the atria. Electrocardiographically, it is characterized by bradycardia, the absence of P waves, and a junctional narrow complex escape rhythm. {ECO:0000269 PubMed:16790700}. Note=The disease may be caused by mutations affecting distinct genetic loci, including the gene represented in this entry. A rare GJA5 genotype has been detected in combination with a mutation in SCN5A in a large family with atrial standstill.
