'''ERCC2''' 或 '''XPD'''是一种涉及转录偶联[[核苷酸切除修复]]的蛋白质。
<!--
The XPD (ERCC2) gene encodes for a 2.3-kb mRNA containing 22 [[exons]] and 21 [[introns]]. The XPD protein is a 760 [[amino acids]] polypeptide with a size of 87kDa. Defects in this gene can result in three different disorders: the cancer-prone syndrome [[xeroderma pigmentosum]] complementation group D, photosensitive [[trichothiodystrophy]], and [[Cockayne syndrome]].<ref>{{cite web | title = Entrez Gene: ERCC2 excision repair cross-complementing rodent repair deficiency, complementation group 2 (xeroderma pigmentosum D)| url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=2068| accessdate = }}</ref>

Just like [[XPB]], XPD is also a part of human transcriptional [[initiation factor]] [[TFIIH]] and has ATP-dependent [[helicase]] activity.<ref name="pmid11092823">{{cite journal | author = Lee TI, Young RA | title = Transcription of eukaryotic protein-coding genes | journal = Annu. Rev. Genet. | volume = 34 | issue = | pages = 77–137 | year = 2000 | pmid = 11092823 | doi = 10.1146/annurev.genet.34.1.77}}</ref> It belongs to the RAD3/XPD subfamily of helicases.

XPD is essential for the viability of cells. Deletion of XPD in mice is embryonic lethal.
