The function of LCMT2 (leucine carboxyl methyltransferase 2, Ensembl gene identifier ENSG00000168806) is as follows. S-adenosyl-L-methionine-dependent methyltransferase that acts as a component of the wybutosine biosynthesis pathway (Probable). Wybutosine is a hyper modified guanosine with a tricyclic base found at the 3'-position adjacent to the anticodon of eukaryotic phenylalanine tRNA (Probable). .
