Abstract
Gamma-tubulin is a centrosomal protein found in microtubule organizing centres (MTOCs) in cells from many different organisms, and has several properties, which makes it a candidate for both the initiation of microtubule assembly and anchorage. Gamma-tubulin is encoded by a single gene tbg-1 in Caenorhabditis elegans. In this paper tbg-1 was studied to understand the essential role of gamma-tubulin in C. elegans. Essential role of tbg-1 expression was confirmed by the disruption of the gene expression by gamma-tubulin anti-sense RNA production in vivo under the heat shock promoter that caused lethality in the nematodes. Expression of tbg-1 deduced from Northern blot analysis during the development revealed differential expression in different developmental stages. Using tbg-1::lacZ fusion gene expression studies in the germ line transformed worms, it was further revealed that gamma-tubulin expression was observed through out the development from embryonic and post-embryonic stages.
