tRNA-modifying enzyme mutations induce codon-specific mistranslation and protei...
Tavares, Joana F.; Davis, Nick K.; Poim, Ana; Reis, Andreia; Kellner, Stefanie; Sousa, Inês; Soares, Ana R.; Moura, Gabriela M. R.; Dedon, Peter C.Protein synthesis rate and accuracy are tightly controlled by the cell and are essential for proteome homoeostasis (proteostasis); however, the full picture of how mRNA translational factors maintain protein synthesis accuracy and co-translational protein folding are far from being fully understood. To address this question, we evaluated the role of 70 yeast tRNA-modifying enzyme genes on protein aggregation an...
Errors in protein synthesis increase the level of saturated fatty acids and aff...
Araújo, Ana Rita D.; Melo, Tânia; Maciel, Elisabete A.; Pereira, Clara; Morais, Catarina M.; Santinha, Deolinda R.; Tavares, Joana F.; Oliveira, HelenaThe occurrence of protein synthesis errors (mistranslation) above the typical mean mistranslation level of 10-4 is mostly deleterious to yeast, zebrafish and mammal cells. Previous yeast studies have shown that mistranslation affects fitness and deregulates genes related to lipid metabolism, but there is no experimental proof that such errors alter yeast lipid profiles. We engineered yeast strains to misincorpo...
