== Disease ==
[https://www.uniprot.org/uniprot/SYYM_HUMAN SYYM_HUMAN] Defects in YARS2 are the cause of myopathy with lactic acidosis and sideroblastic anemia type 2 (MLASA2) [MIM:[https://omim.org/entry/613561 613561]. MLASA2 is a rare oxidative phosphorylation disorder specific to skeletal muscle and bone marrow. Affected individuals manifest sideroblastic anemia, progressive lethargy, muscle weakness, and exercise intolerance associated with persistent lactic acidemia.<ref>PMID:20598274</ref> <ref>PMID:22504945</ref> 
== Function ==
[https://www.uniprot.org/uniprot/SYYM_HUMAN SYYM_HUMAN] 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) (By similarity).<ref>PMID:15779907</ref>
