Mistranslating Trnas Alter The Heat Shock Activation By Hsf1, Rebecca Dib Aug 2022

Mistranslating Trnas Alter The Heat Shock Activation By Hsf1, Rebecca Dib

Undergraduate Student Research Internships Conference

Translation, or the production of protein from an mRNA blueprint, is among the most fundamental processes to life as we know it. tRNAs are essential to accurate translation, as they decode the codons of mRNA and recruit corresponding amino acids. Variant tRNAs with anticodon mutations can decrease translational fidelity by recruiting the incorrect amino acid, an aberrant process known as mistranslation. When proteins are produced with incorrect amino acid sequences, they may misfold. The heat shock response functions to alleviate cellular stress caused by misfolded proteins, either by refolding or targeting misfolded proteins for degradation. Hsf1 acts as a transcriptional …


Probing Large Intrinsically Disordered Regions Through Novel Sortase-Mediated Ligation, Leah Kjormoe May 2020

Probing Large Intrinsically Disordered Regions Through Novel Sortase-Mediated Ligation, Leah Kjormoe

Scholars Week

In the realm of proteins, it is widely accepted that structure informs function. However, there are many proteins that contain intrinsically disordered regions (IDRs). These regions are areas in which the protein lacks defined structure, and IDPs are also often unstable, which complicates structural studies. NMR spectroscopy is an established method for probing protein structure and has been applied to that end in small IDRs. However, larger IDRs often have spectral overlap that makes data difficult to interpret. Furthermore, low-concentration samples limit spectral clarity. One method to address these difficulties is to use sortase ligation and segmental labeling, which increases …
