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 …
