Catalyzes the methyl esterification of L-isoaspartyl and D-aspartyl residues in peptides and proteins that result from spontaneous decomposition of normal L-aspartyl and L-asparaginyl residues. It plays a role in the repair and/or degradation of damaged proteins. Acts on microtubule-associated protein 2, calreticulin, clathrin light chains a and b, Ubiquitin carboxyl- terminal hydrolase isozyme L1, phosphatidylethanolamine-binding protein 1, stathmin, beta-synuclein and alpha-synuclein (By similarity).

Titration of the PIMT antibody may be required due to differences in protocols and secondary/substrate sensitivity.

A portion of amino acids 18-55 from the human protein was used as the immunogen for the PIMT antibody.

Aliquot the PIMT antibody and store frozen at -20oC or colder.Avoid repeated freeze-thaw cycles.
