除了具有Cx43同源物外,斑马鱼基因组还包含一个类似Cx43的基因Cx40.8。本研究探讨了cx40.8在斑马鱼鳍中的表达及cx40.8在HeLa细胞中的功能。我们发现cx40.8存在于与cx43相同的分裂细胞群中。与Cx43不同的是,染料偶联实验表明Cx40.8只能低效地形成功能性的间隙连接通道。然而,共转染发现Cx40.8可以与Cx43在间隙连接斑块中共定位,并且由此产生的斑块包含功能性的间隙连接通道。综上所述,这些数据表明Cx40.8可能在功能上与Cx43相互作用以调节体内细胞增殖。
In addition to having a Cx43 ortholog, the zebrafish genome also contains a Cx43-like gene, Cx40.8. Here, we investigate the expression of cx40.8 in zebrafish fins and the function of Cx40.8 in HeLa cells. We find that cx40.8 is present in the same population of dividing cells as cx43. Unlike Cx43, dye coupling assays suggest that Cx40.8 only inefficiently forms functional gap junction channels. However, co-transfection reveals that Cx40.8 can co-localize with Cx43 in gap junction plaques, and that the resulting plaques contain functional gap junction channels. Together, these data suggest the possibility that Cx40.8 may functionally interact with Cx43 to regulate cell proliferation in vivo.
