Cockayne syndrome (CS) is an inherited disorder that involves photosensitivity, developmental defects, progressive degeneration and characteristics of premature aging. Evidence indicates primarily nuclear roles for the major CS proteins, CSA and CSB, specifically in DNA repair and RNA transcription. We reveal herein a complex regulation of CSB targeting that involves three major consensus signals: NLS1 (aa467-481), which directs nuclear and nucleolar localization in cooperation with NoLS1 (aa302-341), and NLS2 (aa1038-1055), which seemingly optimizes nuclear enrichment.

The Cockayne Syndrome Protein B (CSB) plays an essential role in Transcription-Coupled Nucleotide Excision Repair (TC-NER) by recruiting repair proteins once transcription is blocked with a DNA lesion. In fact, CSB-deficient cells are unable to recover from transcription-blocking DNA lesions. 5-Aza-2'-deoxycytidine (5-azadC) is a nucleoside analogue that covalently traps DNA methyltransferases (DNMTs) onto DNA.

The structure-specific ERCC1-XPF endonuclease plays a key role in DNA damage excision by nucleotide excision repair (NER) and interstrand crosslink repair. Mutations in this complex can either cause xeroderma pigmentosum (XP) or XP combined with Cockayne syndrome (XPCS-complex) or Fanconi anemia. However, most patients carry compound heterozygous mutations, which confounds the dissection of the phenotypic consequences for each of the identified XPF alleles. Read More

The ATP-dependent chromatin remodeler CSB is implicated in a variety of different DNA repair mechanisms, including transcription-coupled nucleotide excision repair (TC-NER), base excision repair and DNA double strand break (DSB) repair. However, how CSB is regulated in these various repair processes is not well understood. Here we report that the first 30 amino acids of CSB along with two phosphorylation events on S10 and S158, previously reported to be required for CSB function in homologous recombination (HR)-mediated repair, are dispensable for repairing UV-induced DNA damage, suggesting that the regulation of CSB in these two types of repair are carried out by distinct mechanisms.

Transcription-coupled nucleotide excision repair factor Cockayne syndrome protein B (CSB) was suggested to function in the repair of oxidative DNA damage. However thus far, no clear role for CSB in base excision repair (BER), the dedicated pathway to remove abundant oxidative DNA damage, could be established. Using live cell imaging with a laser-assisted procedure to locally induce 8-oxo-7,8-dihydroguanine (8-oxoG) lesions, we previously showed that CSB is recruited to these lesions in a transcription-dependent but NER-independent fashion.

In response to transcription-blocking DNA lesions such as those generated by UV irradiation, cells activate a multipronged DNA damage response. This response encompasses repair of the lesions that stall RNA polymerase (RNAP) but also a poorly understood, genome-wide shutdown of transcription, even of genes that are not damaged. Over the past few years, a number of new results have shed light on this intriguing DNA damage response at the structural, biochemical, cell biological, and systems biology level. Read More

Cockayne syndrome (CS) is a severe disorder with no effective treatment. The Cockayne syndrome group B (CSB) gene is one gene responsible for CS and also causes UV sensitive syndrome (UVS), a disorder that causes mild symptoms. How the CSB gene determines a patient's fate is unknown, but one intriguing point is that in UVS patient cell, there are nonsense mutations in both alleles at the same position in each upstream region of the PiggyBac transposable element derived 3 (PGBD3) inserted region.

Transcription-blocking DNA lesions are removed by transcription-coupled nucleotide excision repair (TC-NER) to preserve cell viability. TC-NER is triggered by the stalling of RNA polymerase II at DNA lesions, leading to the recruitment of TC-NER-specific factors such as the CSA-DDB1-CUL4A-RBX1 cullin-RING ubiquitin ligase complex (CRL). Despite its vital role in TC-NER, little is known about the regulation of the CRL complex during TC-NER. Read More
