Protein Name: Tryptophan--tRNA ligase, cytoplasmic

UniprotKB/SwissProt ID: P17248 (P17248)

Gene Name: WARS1

Organism: Bos taurus (Bovine)

Function: T1-TrpRS has aminoacylation activity while T2-TrpRS lacks it. T1-TrpRS and T2-TrpRS possess angiostatic activity. 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 (By similarity)
