function:Probable S-adenosyl-L-methionine-dependent methyltransferase that acts as a component of the wybutosine biosynthesis pathway. Wybutosine is a hyper modified guanosine with a tricyclic base found at the 3'-position adjacent to the anticodon of eukaryotic phenylalanine tRNA (By similarity). May methylate the carboxyl group of leucine residues to form alpha-leucine ester residues.,pathway:tRNA modification; wybutosine-tRNA(Phe) biosynthesis.,similarity:Belongs to the methyltransferase superfamily. LCMT family.,subunit:Interacts with RNF144B/IBRDC2.,
