TRM1

L000002337, YDR120C
tRNA methyltransferase; two forms of protein are made by alternative translation starts; localizes to both nucleus and mitochondrion to produce modified base N2,N2-dimethylguanosine in tRNAs in both compartments; nuclear Trm1p is evenly distributed around inner membrane in WT, but mislocalizes as puncta near ER-nucleus junctions in spindle pole body (SPB) mutants; both Trm1p inner nuclear membrane targeting and maintenance depend upon SPB

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

Trm11p and Trm112p are both required for the formation of 2-methylguanosine at position 10 in yeast tRNA.

N(2)-Monomethylguanosine-10 (m(2)G10) and N(2),N(2)-dimethylguanosine-26 (m(2)(2)G26) are the only two guanosine modifications that have been detected in tRNA from nearly all archaea and eukaryotes but not in bacteria. In Saccharomyces cerevisiae, formation of m(2)(2)G26 is catalyzed by Trm1p, and we report here the identification of the enzymatic activity that catalyzes the formation of m(2)G10 in yeast tRNA. It is composed of ... [more]
