Electronic Thesis and Dissertation Repository
The regulation of transcription is an important cellular function because it is the first step in gene regulation. In Saccharomyces cerevisiae, two protein complexes, SAGA and NuA4, act as regulators of transcription. A common protein shared between these two complexes, called Tra1, regulates transcriptional activation through its interaction with gene specific transcriptional activators. Tra1 is a member of the PIKK family of proteins, which are characterized by FAT, PI3K and FATC domains. The FATC domain encompasses the terminal 33-35 residues of the protein. Two mutations within the FATC domain, tra1-L3733A and tra1-F3744A, result in slow growth under stress …

Transcribed exons in genes are joined together at donor and acceptor splice sites precisely and efficiently to generate mRNAs capa ble of being translated into proteins. The sequence variability in individual splice sites can be modeled using Shannon information theory. In the laboratory, the degree of individual splice site use is inferred from the structures of mRNAs and their relative abundance. These structures can be predicted using a bipartite information theory framework that is guided by current knowledge of biological mechanisms for exon recognition. We present the results of this analysis for the complete dataset of all expressed human exons.
