Changes In Cell Morphology And The Cellular Localization Of Protein Kinase Dsk1 In Schizosaccharomyces Pombe In Response To Butylated Hydroxyanisole, Jacqueline T. Humphries

Scripps Senior Theses

Dsk1 is the Schizosaccharomyces pombe functional homolog of human SRPK1, an SR protein kinase that regulates localization and function of SR protein splicing factors involved in transcription, alternative splicing, and mRNA export. It has been shown that a Dsk1 deletion strain of S. pombe is sensitive to exposure to butylated hydroxyanisole (BHA), a phenol derivative commonly used as a food preservative. Little is known about how BHA interacts with cells on a functional level, although it has been shown to be cytotoxic and tumorigenic. The aims of this thesis are to study the effect of BHA on eukaryotic cells and ...
