Abstract
In C. elegans the unc-119 gene is expressed throughout the nervous system of both the embryo and adult and encodes a novel protein product (Maduto & Pilgrim, 1995). Due to its pan-neuronal expression it was thought that unc-119 would play a basic role in the development of the nematode nervous system. We wished to determine whether this family of genes is expressed during development and in non-retinal tissues in vertebrates. To address these questions we chose to investigate the expression pattern of the unc-119 homologue in the zebrafish. The zebrafish (Danio rerio) is a popular vertebrate model system that combines the ease of genetic manipulation with embryological analyses. In this thesis, results are described that suggest there are at least three unc-119 homologues in the zebrafish genome. Two of these homologues (unc119b & unc119c) are expressed in non-retinal embryonic and adult tissues; the expression pattern of the third homologue, unc119a, has not been determined. These findings suggest that the unc-119 gene homologues in mammals (e.g. HRG4 and RRG4) may have a more widespread expression pattern (e.g. extra-retinal) than previously thought.
