Expression profiles of the novel human connexin genes hCx30.2, hCx40.1, and hCx62 differ from their putative mouse orthologues.
In this study we show by Northern blot hybridization that the novel human (h) connexin (Cx) genes hCx25, hCx30.2, hCx31.9, hCx40.1, hCx59, and hCx62 are transcribed in different adult tissues. The hCx25 RNA is slightly expressed in placenta, and hCx59 and hCx62 RNA are both transcribed in skeletal muscle, although the latter is also slightly expressed in heart. Expression profiles of three orthologous human (h) and mouse (m) connexin gene pairs, i.e., hCx30.2 versus mCx29, hCx40.1 versus mCx39, and hCx62 versus mCx57, differ strongly, in contrast to other orthologous connexins with higher sequence identities. Thus, several of the new human connexin genes appear to have evolved to different expression patterns and presumably to different functions compared to their orthologues in the mouse genome. (121)
