| - | [ | + | [https://www.uniprot.org/uniprot/URM1_YEAST URM1_YEAST] Acts as a sulfur carrier required for 2-thiolation of mcm(5)S(2)U at tRNA wobble positions. Serves as sulfur donor in tRNA 2-thiolation reaction by being thiocarboxylated (-COSH) at its C-terminus by UBA4. The sulfur is then transferred to tRNA to form 2-thiolation of mcm(5)S(2)U. Prior mcm(5) tRNA modification by the elongator complex is required for 2-thiolation. May also act as an ubiquitin-like protein that is covalently conjugated to other proteins such as AHP1; the relevance of such function is however unclear in vivo. Indirectly involved in oxidative stress response and regulation of budding and haploid invasive growth.<ref>PMID:10713047</ref> <ref>PMID:14555475</ref> <ref>PMID:14551258</ref> <ref>PMID:18664566</ref> <ref>PMID:18755837</ref> <ref>PMID:19145231</ref> <ref>PMID:19151091</ref> |
