(IGF1R = insulin-like growth factor 1 receptor; PCNA = proliferating cell nuclear antigen; RAD18 = E3 ubiquitin-protein ligase RAD18; SHPRH = E3 ubiquitin-protein ligase SHPRH) PMID: 28924044

28. Reduced affinity of PCNA(S228I) for specific clients causes subtle cellular defects in undamaged cells which likely contribute to the etiology of PCNA-associated DNA repair disorder (PARD).
