Aminoacyl-tRNA synthetases catalyze the first step of protein synthesis. that consists of the aminoacylation of tRNAs. Recently we shown that one of the tRNA synthetases-human tyrosyl-tRNA synthetase (TyrRS)-offers novel cytokine functions in addition to its part in protein synthesis (1). This demonstration founded a link between protein synthesis and transmission transduction. Under apoptotic conditions in… Continue reading Aminoacyl-tRNA synthetases catalyze the first step of protein synthesis. that consists
