Rabbit anti-Human PCMT1 Polyclonal Antibody, HRP conjugated

Uniprot Id

P22061

Target Species

Human

Target Name

PCMT1

Target Full Name

Protein-L-isoaspartate(D-aspartate) O-methyltransferase

Target Function

Initiates the repair of damaged proteins by catalyzing methyl esterification of L-isoaspartyl and D-aspartyl residues produced by spontaneous isomerization and racemization of L-aspartyl and L-asparaginyl residues in aging peptides and proteins. Acts on EIF4EBP2, microtubule-associated protein 2, calreticulin, clathrin light chains a and b, Ubiquitin C-terminal hydrolase isozyme L1, phosphatidylethanolamine-binding protein 1, stathmin, beta-synuclein and alpha-synuclein.

Target Subcellular Location

Cytoplasm, cytosol.

Target Protein Families

Methyltransferase superfamily, L-isoaspartyl/D-aspartyl protein methyltransferase family

Target Synonyms

PCMT1; Protein-L-isoaspartate(D-aspartate) O-methyltransferase; PIMT; EC 2.1.1.77; L-isoaspartyl protein carboxyl methyltransferase; Protein L-isoaspartyl/D-aspartyl methyltransferase; Protein-beta-aspartate methyltransferase

Target Background

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.
