State Note: Based on the distinct PTM states in diseases, PTMD classified all disease-associated PTMs into six classes, including whether the up-regulation (U) or down-regulation (D) of PTM levels, the absence (A) or presence (P) of PTMs, and the creation (C) or disruption (N) of PTM sites are associated with diseases.
