ERCC2
ERCC2, or XPD is a protein involved in transcription-coupled nucleotide excision repair.
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.[1]
Just like XPB, XPD is also a part of human transcriptional initiation factor TFIIH and has ATP-dependent helicase activity.[2] 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.
