Characterization Of Regulatory Mechanisms For Alternative Splicing In Alpha Thyroid Hormone Receptor Mrna, Chao Zhang

Master's Theses (2009 -)

In eukaryotes, alternative splicing is an essential post transcriptional modification process for functional gene expression and a major contributor to protein diversity. The regulation of alternative splicing generally involves the engagements of RNA sequences cis-acting elements) and corresponding protein factors (trans-acting factors). The cisacting RNA motifs can be categorized depending on positional and functional differences. Trans-acting protein factors will then bind to RNA sequences and affect the corresponding splicing activity. Recently, factors associated with 3’ polyadenylation have also been identified to affect alternative splicing.

In mammals, the α-thyroid hormone receptor gene (TRα) produces transcripts for two functionally antagonistic isoforms, TRα1 …
