靶點詳情

功能：

Structural component of eye lens gap junctions. Gap junctions are dodecameric channels that connect the cytoplasm of adjoining cells. They are formed by the docking of two hexameric hemichannels, one from each cell membrane. Small molecules and ions diffuse from one cell to a neighboring cell via the central pore.

1. this study identified the genetic susceptibility of GJA8 polymorphisms on ARC and provides new clues for fully understanding the pathological mechanism of GJA8 variants in affecting lens opacity PMID: 30349978
2. The mutation c.139G>A in the GJA8 gene detected in the present study was also previously reported in Caucasian and Chinese families but with different phenotypes, i.e. nuclear and nuclear pulverulent cataracts. Thus, the mutation c.139G>A in GJA8 appears to exhibit marked interfamilial phenotypic variability. PMID: 30262699
3. The p.V44M mutation in the GJA8 gene was the most common mutation and was due to a founder effect within the Chinese congenital cataract cohort studied. PMID: 30078984

6. Study identified two novel missense mutations within P59 and R76 of Cx50 that are associated with autosomal dominant congenital cataracts (ADCC).

20. a novel G>A mutation of GJA8 in a three-generation Chinese pedigree was associated with perinuclear opacities of the lens involving the nucleus PMID: 23555834
21. Data indicate that after inhibition of new protein synthesis with cycloheximide, CX50fs disappeared much more rapidly than CX50, suggesting increased degradation of the mutant. PMID: 23720739
22. A novel connexin 50 gene (GJA8) mutation, resulting in the amino substitution p. D47H in a Chinese family with nuclear and zonular pulverulent congenital cataracts, is reported. PMID: 23592913
