초록

Conncxin (Cx) is an important and essential protein induction of oocyte maturation, which is present in almost all mammalian tissucs except cirulating blood cells and adult skeletal museles. In this study, goldfish Cx43 cDNA sequence is available in GenBank under the accession number AB078505. Homology analyses using the GenBank and EMBL general database searches indicated that goldfish Cx43 cDNA has a high homology with carp Cx43 (95.1% identity), zebrafish Cx43 (90.5% identity), and chicken Cx43 (81.9% identity). Goldfish Cx43 is similar to the Cx family in its general features, and all the typical Cx consensus sequences are also found. Moreover, significantly increased Cx43 transcrpts were observed in mature goldfish (GSI; 18.3-21.7) pituitary and ovary when compared with immature goldfish (GSI; 4.9-6.0). Cx43 transeripts were weakly detectrd in both liver and kidney of immature and mature goldfish. There is possible that Cx43 nctivity was relation to oocyte maturation in the goldfish.
