From: Isoaspartic acid is present at specific sites in myelin basic protein from multiple sclerosis patients: could this represent a trigger for disease onset?

Deamidation of Gln147 in MBP from controls () and multiple sclerosis (MS) patients suffering from SPMS () PPMS () and RRMS (). Deamidation of Gln147 was measured using the tryptic peptide GVDAQGTSK (i.e. GVDAQGTSK to GVDAEGTSK). Deamidation was significantly greater in the multiple sclerosis patients (p < 0.001, Mann–Whitney-U.). Deamidation increased with age in controls (R 2 = 0.571, p = 0.011)
