| TFIIH is shown to complement three different cell extracts deficient in excision repair : XPB / ERCC3 , XPC and XPD / ERCC2 . ^^^ The complementation of XPB and XPD is a consequence of ERCC 3 and ERCC 2 being integral subunits of TFIIH , whereas complementation of XPC is due to an association of this polypeptide with TFIIH . ^^^ |

| Furthermore , reconstitution of the human excision nuclease was observed with a mixture of five repair factors ( XPA , XPC , XPG , TFIIH , and RPA ) and the recombinant XPF ERCC 1 , thus verifying that no additional protein factors are needed for the specific dual incisions characteristic of human excision repair . . ^^^ |

| We show that , while XPA binding to damaged DNA is ATP independent , stable association of TFIIH with DNA lesions is promoted by ATP hydrolysis and is dependent on the integrity of XPA and XPC proteins in the cell extract . ^^^ |

| Here we demonstrate that XPC HR23B interacts with general transcription factor IIH ( TFIIH ) both in vivo and in vitro . ^^^ This interaction is thought to be mediated through the specific affinity of XPC for the TFIIH subunits XPB and / or p 62 , which are essential for both basal transcription and nucleotide excision repair . ^^^ Interestingly , association of TFIIH with DNA was observed in both wild type and XP A cell extracts but not in XP C cell extracts , and XPC HR23B could restore the association of TFIIH with DNA in XP C cell extracts . ^^^ Moreover , we found that XPC HR23B was necessary for efficient association of TFIIH with damaged DNA in cell free extracts . ^^^ We conclude that the XPC HR23B protein complex plays a crucial role in the recruitment of TFIIH to damaged DNA in global genome repair . . ^^^ |

| Tumor suppressor p 53 dependent recruitment of nucleotide excision repair factors XPC and TFIIH to DNA damage . ^^^ In this study , the regulatory effect of p 53 , on the spaciotemporal recruitment of XPC and TFIIH to DNA damage sites , was investigated in repair proficient and deficient human cells in situ . ^^^ Colocalization experiments of the NER factors showed that in normal human cells , XPC and TFIIH are rapidly and efficiently recruited to DNA damage within SNS . ^^^ By contrast , recruitment of both XPC and TFIIH to DNA damage in SNS occurred much less efficiently in p 53 Null or p 53 compromised cells . ^^^ The results also showed that dispersal of recruited XPC and TFIIH from DNA damage SNS occurs within a short period after DNA damage . ^^^ |

| We propose a recognition mechanism by which the low specificity recognition factors , RPA , XPA , and XPC , act in a cooperative manner to locate the lesion and , aided by the kinetic proofreading provided by TFIIH , form a high specificity complex at the damage site that initiates removal of thymine dimers at a physiologically relevant rate and specificity . . ^^^ |

| TFIIH is then recruited and , in the presence of ATP , extends the opening from position 6 to +6 ; it also displaces XPC downstream from the lesion , thereby providing the topological structure for recruiting XPA and RPA , which will enlarge the opening . ^^^ XPG and XPF / ERCC1 endonucleases then cut the damaged DNA at the limit of the opened structure that was previously `` labeled ' ' by the positioning of XPC / HR23B and TFIIH . . ^^^ |
