For example, a classic T‐cell epitope (YMDGTMSQV) formed by PTM of tyrosinase specifically occurs in melanoma (Skipper et al., 1996) and alteration in glycosylation patterns seen in melanoma (Laidler et al., 2005) can increase the number of targets for tumour‐specific antibodies (Kotlan et al., 2019). The gene discussed is TYR; the disease is melanoma.
