physiological function | lysyl-tRNA synthetase (KRS) is a multi-functional enzyme, which, in addition to its primary function of aminoacylation of lysine onto the cognate tRNA, has various noncanonical functions. Enzyme KRS interacts with the laminin receptor (LR/RPSA) and enhances laminin-induced cell migration in cancer metastasis. The anticodon-binding domain of KRS binds directly to the C-terminal region of 37 kDa laminin receptor precursor 37LRP, and inhibitors BC-K-01 and BC-K-YH16899 interfere with KRS37LRP binding. In addition, the anticodon-binding domain of KRS binds to laminin. Furthermore, KRS is a major source of diadenosine tetraphosphate (Ap4A) in immunologically activated mast cells, and via translocation into the nucleus, KRS controls the expression of microphthalmia-associated transcription factor (MITF)-inducible genes in allergic responses | Homo sapiens |
