PCMT1 Antibody / Protein-L-isoaspartate (D-aspartate) O-methyltransferase

Protein-L-isoaspartate (D-aspartate) O-methyltransferase is an enzyme that in humans is encoded by the PCMT1 gene. This gene encodes a member of the type II class of protein carboxyl methyltransferase enzymes. The encoded enzyme plays a role in protein repair by recognizing and converting D-aspartyl and L-isoaspartyl residues resulting from spontaneous deamidation back to the normal L-aspartyl form. The encoded protein may play a protective role in the pathogenesis of Alzheimer's disease, and single nucleotide polymorphisms in this gene have been associated with spina bifida and premature ovarian failure. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
