Protein
tRNA (adenine(58)-N(1))-methyltransferase non-catalytic subunit TRM6
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Substrate-binding subunit of tRNA (adenine-N(1)-)-methyltransferase, which catalyzes the formation of N(1)-methyladenine at position 58 (m1A58) in initiator methionyl-tRNA (PubMed:10779558, PubMed:9851972). Also required for repression of GCN4 mRNA translation by the upstream open reading frames (uORFs) under conditions of amino acid sufficiency (PubMed:7542616).
Similarity
Belongs to the TRM6/GCD10 family.
