靶點(diǎn)詳情

功能：

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.
基因功能參考文獻(xiàn)：
1. Atrial Fibrillation (AF)-linked Cx40 mutants impair gap junction and/or hemichannel function, which may predispose the mutant carriers to AF. PMID: 29587382

5. Cx 40 (rs35594137) was associated with atrial fibrillation; in the Uygur population, Cx 40 (rs35594137) should be considered as an independent risk factor for patients with atrial fibrillation, who might have racial differences in rs35594137 variant frequencies PMID: 26634538

Multiple impairments were observed in these mutants, including impaired gap junction function by abnormal localization or function, as well as increased hemichannel function. PMID: 24656738
7. Human atrial myocytes express Cx40 and Cx43. However, in vitro expression study indicates that human Cx40 is not able to dock with Cx43 to form heterotypic gap junction channels.

13. These findings provide evidence that the connexin 40 Q49X mutant is capable of impairing gap-junction distribution and function of key atrial connexins, which might play a role in the predisposition to and onset of atrial fibrillation. PMID: 24626989
14. heterozygous Cx40A96S mice exhibit prolonged episodes of induced atrial fibrillation and severely reduced atrial conduction velocities similar to the corresponding human patient. PMID: 24060583

16. the germline familial mutations in Cx40 impair the gap junctions through different mechanisms, which may predispose the mutant carriers to AF. PMID: 23348765
17. Presence of the Cx40 minor allele (-44 G --> A) results in a uniform down-regulation of right atrial appendage Cx40 protein which was not significantly related to development of post-operative AF. PMID: 22423256
18. Pro265Ser variant in the carboxyl-terminus of connexin 40 alters GAP junctions and increases risk for tetralogy of Fallot. PMID: 22713807
19. Genotyping of rs10465885 showed that the patients with early-onset lone AF were more likely to carry the A allele compared with controls (odds ratio = 1.30; P = 0.011). PMID: 23040431
20. Cx40 coding SNPs are uncommon in atrial fibrillation populations, although rare mutations in this gene may lead to atrial fibrillation pathogenesis. PMID: 23134779

24. Heteromeric cotransfection of Cx40-WT and Cx40-Q58L resulted in homogenous distribution of proteins in the plasma membrane rather than in membrane plaques in approximately 50% of cells; well-defined gap junctions were observed in other cells. PMID: 22247482

34. The -44A allele & -44AA genotype were significantly more frequent in subjects with prior AF than in those without, providing strong evidence linking Cx40 polymorphisms to enhanced atrial vulnerability and increased risk of AF. PMID: 15297374
35. Coinheritance of Cx40 polymorphisms is a possible genetic factor that modifies the clinical manifestation of this inherited arrhythmia. PMID: 16188595
36. We conclude that decidual secretion of growth factors, such as EGF, may act to prime trophoblast for migration/invasion through modulation of connexin expression and function. PMID: 16545451
