Discovery And Characterization Of Small Molecule Inhibitors Of Bromodomains, Md Rezaul Karim
Discovery And Characterization Of Small Molecule Inhibitors Of Bromodomains, Md Rezaul Karim
USF Tampa Graduate Theses and Dissertations
The epigenetic “reader” modules bromodomains (BRDs) exert their diverse cellular functions through the recognition of acetylated lysines on histones and other proteins. Small molecule inhibitors of bromodomains have emerged as a promising therapeutic strategy to treat atherosclerotic cardiovascular diseases and cancers. Therefore, a large number of small molecule bromodomain inhibitors have been developed in the last decade, some of which are currently being assessed in the clinic. However, the success of bromodomain inhibitors is currently limited to the bromodomain and extra-terminal domain (BET) subfamily.
To address these, bromodomains outside the BET subfamily (non-BETs) such as TAF1, BRD7/9, TRIM28, and BRD8 …
Intrinsic Disorder Where You Least Expect It: The Incidence And Functional Relevance Of Intrinsic Disorder In Enzymes And The Protein Data Bank, Shelly Deforte
Intrinsic Disorder Where You Least Expect It: The Incidence And Functional Relevance Of Intrinsic Disorder In Enzymes And The Protein Data Bank, Shelly Deforte
USF Tampa Graduate Theses and Dissertations
Intrinsically disordered proteins (IDPs) and intrinsically disordered protein regions (IDPRs) exist as interconverting conformational ensembles, without a single fixed three-dimensional structure in vivo. The focus in the literature up to this point has been primarily on IDPs that are mostly or entirely disordered. Therefore, we have an incomplete understanding of the incidence and functional relevance of IDPRs in proteins that have regions of both order and disorder. This work explores these populations, by examining IDPRs in the Protein Data Bank (PDB) and in enzymes. By applying disorder prediction methods combined with an analysis of missing regions in crystal structure data, …
Structure, Dynamics, And Evolution Of The Intrinsically Disordered P53 Transactivation Domain, Wade Michael Borcherds
Structure, Dynamics, And Evolution Of The Intrinsically Disordered P53 Transactivation Domain, Wade Michael Borcherds

in numerous disease states, including cancers and neurodegenerative diseases. All proteins are dynamic in nature, occupying a range of conformational flexibilities. This inherent flexibility is required for their function, with ordered proteins and IDPs representing the least flexible, and most flexible, respectively. As such IDPs possess little to no stable tertiary or secondary structure, they instead form broad ensembles of heterogeneous structures, which fluctuate over multiple time scales. Although IDPs often lack stable secondary structure they can assume a more stable structure in the presence of their binding partners in a coupled folding binding reaction.
The phenomenon of the dynamic …
