GeneDescription Connexins, or gap junction proteins, are a family of structurally-related transmembrane proteins that assemble to form vertebrate gap junctions. Each gap junction is composed of two hemichannels, or connexons, which are themselves each constructed out of six connexin molecules. Gap junctions are essential for many physiological processes, such as the coordinated depolarization of cardiac muscle, and proper embryonic development.
GeneFunction Cheng et al. (2003) reported the zebrafish mRNA expression of Cx 48.5,Cx44.1,Cx43 during lens development, both by RT-PCR as well as by whole mount in situ hybridization. It was found that Cx 48.5 is strongly expressed throughout the lens except the lateral lens epithelium, at 36 hours post fertilization. This pattern remained same till 2 days post fertilization. But by 3and 4 dpf the expression was restricted to the differentiating lens fibers in the equatorial and medial regions.Cheng et al. (2004) described the isolation and characterization of zebrafish Cx 48.5. Expression analysis showed that Cx48.5 is expressed in the adult and embryonic lens and heart, adult testis, and transiently in the embryonic otic vesicles. It was seen that morpholino treated embryos developed small lenses and eyes as well as suffered from severe cardiovascular disease.
