Predicted to enable protein-L-isoaspartate (D-aspartate) O-methyltransferase activity. Predicted to act upstream of or within protein modification process. Predicted to be located in membrane. Predicted to be active in cytoplasm. Is expressed in central nervous system. Orthologous to human PCMTD1 (protein-L-isoaspartate (D-aspartate) O-methyltransferase domain containing 1).
