N1 - Funding Information: This work was supported by a grant from Cancer Research UK (to J.Q.S.). Work in the Svejstrup, Mullender, Vermeulen, and Egly laboratories was supported by a grant from the European Community (Integrated Project DNA repair, grant no. LSHG-CT-2005-512113). P.-O.M. and G.G.-M. were funded by the Association for International Cancer Research (AICR 07-0129), a “Young Researcher Program” ATIP(CNRS)/InCa (France), and Association pour la Recherche contre le Cancer (ARC, France) (contract for equipment n: 8505). We thank Dr Camille Godon for the technical assistance, Dr. Dominik Boos for suggestions, and Svejstrup lab members for helpful discussions.

N2 - Transcription-coupled nucleotide excision repair (TC-NER) allows RNA polymerase II (RNAPII)-blocking lesions to be rapidly removed from the transcribed strand of active genes. Defective TCR in humans is associated with Cockayne syndrome (CS), typically caused by defects in either CSA or CSB. Here, we show that CSB contains a ubiquitin-binding domain (UBD). Cells expressing UBD-less CSB (CSBdel) have phenotypes similar to those of cells lacking CSB, but these can be suppressed by appending a heterologous UBD, so ubiquitin binding is essential for CSB function. Surprisingly, CSBdel remains capable of assembling nucleotide excision repair factors and repair synthesis proteins around damage-stalled RNAPII, but such repair complexes fail to excise the lesion. Together, our results indicate an essential role for protein ubiquitylation and CSB's UBD in triggering damage incision during TC-NER and allow us to integrate the function of CSA and CSB in a model for the process.
