ERCC2 and xeroderma pigmentosum group A: Bulky platinum-DNA adducts are mainly repaired by the nucleotide excision repair pathway, in which proteins of the excision repair cross-complementation 1 (ERCC1), xeroderma pigmentosum group D (XPD, also known as ERCC2) and X-ray repair cross-complementing group (XRCC), have important roles [13,21].
