靶點詳情

  • 功能：
    Isoform 1, isoform 2 and T1-TrpRS have aminoacylation activity while T2-TrpRS lacks it. Isoform 2, T1-TrpRS and T2-TrpRS possess angiostatic activity whereas isoform 1 lacks it. T2-TrpRS inhibits fluid shear stress-activated responses of endothelial cells. Regulates ERK, Akt, and eNOS activation pathways that are associated with angiogenesis, cytoskeletal reorganization and shear stress-responsive gene expression.
  • 基因功能參考文獻：
    1. Based on these results, secretion of full-length tryptophanyl-tRNA synthetase appears to work as a primary defence system against infection, acting before full activation of innate immunity. PMID: 27748732
