Custom tRNA Synthetase Service

tRNA synthetase - enzyme is also named aminoacyl-tRNA synthetase (aaRSs). In the first step of protein synthesis, each enzyme can exquisitely link the respective amino acid to its cognate tRNA isoform. This diverse set of proteins is united by a common aminoacylation reaction, which attaches an amino acid to its cognate tRNA. In humans, 20 different types of aa-tRNA are composed of 20 different aminoacyl-tRNA synthetases, each corresponding to each amino acid in the genetic code. There are two classes of tRNA synthetases divided based on their chemical properties, architecture of their catalytic domains and consensus sequences.

These tRNA synthetases control gene expression within the cell of origin, and when released exert homeostatic and developmental control in specific human cell types, tissues and organs during adult or fetal development or both. Non-translational functions of tRNA synthetases, affecting the pathways for cardiovascular development, immune response and mTOR, IFN-γ and p5 signaling, have recently been discovered. And those new functions play an important role in the stability of the intracellular environment (Figure 1). The associations of tRNA synthetases with specific diseases has also stimulated investigations of disease mechanisms. Since they are essential, the tRNA synthetases have become drug targets for the development of drugs and antibiotics. In recent years, the discovery of important new functions of this protein family has provided new and promising ways to treat the development of various human diseases.
