Function
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.[1] [2] [3] [4] [5] [6] [7]
