Protein

tRNA (adenine(58)-N(1))-methyltransferase catalytic subunit TRM61

Gene

GCD14

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalytic subunit of tRNA (adenine-N1-)-methyltransferase, which catalyzes the formation of N1-methyladenine at position 58 (m1A58) in initiator methionyl-tRNA (PubMed:10779558, PubMed:9851972). GCD14 is also required for repression of GCN4 mRNA translation by the upstream open reading frames (uORFs) under conditions of amino acid sufficiency (PubMed:9539420).3 Publications

Miscellaneous

Present with 7220 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

S-adenosyl-L-methionine + adenine(58) in tRNA = S-adenosyl-L-homocysteine + N1-methyladenine(58) in tRNA.PROSITE-ProRule annotation
