===Crystal structure of human prolyl-tRNA synthetase (halofuginone bound form)=== | |||
==Function== | |||
[[http://www.uniprot.org/uniprot/SYEP_HUMAN SYEP_HUMAN]] Catalyzes the attachment of the cognate amino acid to the corresponding tRNA in a two-step reaction: the amino acid is first activated by ATP to form a covalent intermediate with AMP and is then transferred to the acceptor end of the cognate tRNA. Component of the GAIT (gamma interferon-activated inhibitor of translation) complex which mediates interferon-gamma-induced transcript-selective translation inhibition in inflammation processes. Upon interferon-gamma activation and subsequent phosphorylation dissociates from the multisynthetase complex and assembles into the GAIT complex which binds to stem loop-containing GAIT elements in the 3'-UTR of diverse inflammatory mRNAs (such as ceruplasmin) and suppresses their translation.<ref>PMID:1756734</ref> <ref>PMID:15479637</ref> <ref>PMID:23071094</ref> | |||
