Can Chaperones Promote Protein Splicing?, Hazel Thomas Apr 2025

Can Chaperones Promote Protein Splicing?, Hazel Thomas

Honors College Theses

Inteins are a mobile genetic element hypothesized to function as regulatory molecules in microbes. They bear a homing endonuclease domain for genome traversal, as well as specific residues allowing for protein splicing. In the protein splicing reaction, the intein is removed and the flanking residues, termed exteins, are ligated together with a peptide bond to form a functional host protein. Due to their interruption prior to splicing, inteins prevent a host protein from functioning until the intein ligates the two exteins. To measure factors that regulate protein splicing in vivo, an intein-based biosensor based on kanamycin resistance (K …

Compensating Regulatory Losers, Todd S. Aagaard Apr 2025

Compensating Regulatory Losers, Todd S. Aagaard

Faculty Publications

Every change in government regulation creates benefits and burdens that fall unequally on the population. This unequal distribution raises the question of whether fairness requires compensating those who bear regulatory costs—what is known as the “compensation problem.” The extensive body of scholarship addressing the compensation problem tends to focus only on the burdens of regulatory compliance and ignores the burdens of injuries left unaddressed by regulation. The effect of this differential treatment is to treat past regulatory windfalls as permanent entitlements and to omit from the analysis equally deserving regulatory losers who have suffered the consequences of unregulated harms. This …
