Recombinant Human Tyrosine–tRNA ligase, cytoplasmic (YARS)

Uniprot Id

P54577

Target Species

Human

Target Name

YARS

Target Full Name

Tyrosine--tRNA ligase, cytoplasmic

Target Function

Catalyzes the attachment of tyrosine to tRNA(Tyr) in a two-step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr).

Target Involvement

Charcot-Marie-Tooth disease, dominant, intermediate type, C (CMTDIC)

Target Subcellular Location

Cytoplasm.

Target Protein Families

Class-I aminoacyl-tRNA synthetase family

Target Research Area

Metabolism

Target Synonyms

CMTDIC; SYYC_HUMAN; Tyrosine tRNA ligase, cytoplasmic; Tyrosine tRNA ligase 1, cytoplasmic; Tyrosyl tRNA synthetase; Tyrosyl--tRNA ligase; Tyrosyl-tRNA synthetase, cytoplasmic; TyrRS; yars; YRS; YTS

Target Background

Aminoacyl-tRNA synthetases catalyze the aminoacylation of tRNA by their cognate amino acid. Because of their central role in linking amino acids with nucleotide triplets contained in tRNAs, aminoacyl-tRNA synthetases are thought to be among the first proteins that appeared in evolution. Tyrosyl-tRNA synthetase belongs to the class I tRNA synthetase family. Cytokine activities have also been observed for the human tyrosyl-tRNA synthetase, after it is split into two parts, an N-terminal fragment that harbors the catalytic site and a C-terminal fragment found only in the mammalian enzyme. The N-terminal fragment is an interleukin-8-like cytokine, whereas the released C-terminal fragment is an EMAP II-like cytokine.
