Methylates the carboxyl group of the C-terminal leucine residue of protein phosphatase 2A catalytic subunits to form alpha-leucine ester residues. Belongs to the methyltransferase superfamily. LCMT family. 3 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
