Regulation of tubulin gene expression in sea urchin embryosGong, Zhiyuan. January 1987 (has links)
Regulation of tubulin gene expression in embryos of the sea urchin Lytechinus pictus has been experimentally investigated by use of cloned recombinant tubulin DNA and anti-tubulin antiserum. Tubulin synthesis appears to be autogenously regulated at the level of tubulin mRNA stability by the level of unpolymerized tubulin; i.e., the more unpolymerized tubulin, the less stable the tubulin mRNA. Destabilization of tubulin mRNA requires continued protein synthesis. Most of tubulin stored in eggs is unpolymerized; during embryogenesis the mass of tubulin per embryo changes little, but unpolymerized tubulin is increasingly polymerized into microtubules. There is a transcriptional stimulation of tubulin genes at the time of ciliogenesis but thereafter autoregulation by the ontogenetic decrease of the level of unpolymerized tubulin plays a predominant role for an increasing accumulation of tubulin mRNA. Deciliation results in a transient enhancement of transcription of tubulin genes, which is independent of the level of unpolymerized tubulin and does not require protein synthesis.

Localization and characterization of an ectodermal protein of sea urchin embryosMontpetit, Isabelle January 1989 (has links)
In the urchin Strongylocentrotus purpuratus, the expression of the Spec3 gene is associated with the growth of cilia, one of the first morphogenetic events during development. The product of this gene was characterized using an antiserum raised against a peptide corresponding to the predicted amino-terminal portion of the protein. This thesis describes the localization of the Spec3 protein at different stages during embryonic development. Immunocytochemistry indicated that the protein is associated with cilia and Golgi complexes of ectodermal cells. Agents that inhibit protein synthesis and Golgi secretion also altered its normal distribution. Fractionation of cilia and immunoblotting indicate that the protein is associated with the ciliary axoneme and that it behaves as a large aggregate.
