Protein Information (annotations from UniProt)

Database IDHIV0002442
UniProt IDP54136
Primary gene name(s)RARS
Synonym gene name(s)unknown
Protein nameArginine--tRNA ligase, cytoplasmic
Protein functionForms part of a macromolecular complex that catalyzes the attachment of specific amino acids to cognate tRNAs during protein synthesis. Modulates the secretion of AIMP1 and may be involved in generation of the inflammatory cytokine EMAP2 from AIMP1. {ECO:0000269|PubMed:17443684}.
