PCMT1 (protein-L-isoaspartate (D-aspartate) O-methyltransferase), also known as PIMT, is a member of the L-isoaspartyl/D-aspartyl protein methyltransferase family and is highly expressed in brain.
Functioning as a monomer, PCMT localizes to the cytoplasm and participates in the degradation and/or repair of damaged proteins.
More specifically, PCMT1 recognizes isomerized Asp or Asn residues in peptides and proteins and catalyzes the conversion of abnormal L-isoaspartyl and D-aspartyl residues to methyl esters that may then spontaneously hydrolyze to re-form normal aspartyl residues.
In congruence with this reaction, PCMT1 converts the methyl donor S-adenosylmethionine (AdoMet) to S-andenosylhomocysteine (AdoHcy).
In mice lacking PCMT1, damaged proteins accumulate in a variety of tissues and the ratio between AdoMet and AdoHcy is increased in brain tissue.
The phenotypic result is progressive epilepsy and death at an early age.
