Function

TRM61_YEAST Catalytic subunit of tRNA (adenine-N(1)-)-methyltransferase, which catalyzes the formation of N(1)-methyladenine at position 58 (m1A58) in initiator methionyl-tRNA. GCD14 is also required for repression of GCN4 mRNA translation by the upstream open reading frames (uORFs) under conditions of amino acid sufficiency.^{[1] [2] [3]}
