ProteomicsInvestigation of interacting proteins of PROTEIN L-ISOASPARTYL METHYLTRANSFERASE (PIMT) during ShB pathogenesis and identification of isoAsp accumulation in ALDH and PBZ1.
1. The formation of isoAsp residues from Asp and Asn residues in proteins and peptides is accelerated under stressful environments and has detrimental effects on protein structure and function. PROTEIN L-ISOASPARTYL METHYLTRANSFERASE (PIMT) is a protein repairing enzyme which revert such deleterious...

ProteomicsisoAsp analysis of bovine lens alpha-crystallin
Isomerization of Asp residues has been long thought to occur only in a few tissues. Recent reports suggested that such post-translational protein modifications may occur in all tissues and proteins in vivo, including serum. For proof of concept using comprehensive analysis, the MS-based proteomic ap...

ProteomicsIdentification of peptide isoforms in gS-crystallin using stable isotope labeled peptides
ɣS-crystallin is a major protein of the human lens and is highly modified with age and cataract due to a lack of lens protein turnover. Previous studies have identified some sites of isomerization and racemization of deamidated asparaginyl and aspartyl residues in ɣS but have been limited due to the...
