Interaction between the Cockayne syndrome B and p53 proteins: implications for aging
The CSB protein plays a role in the transcription coupled repair (TCR) branch of the nucleotide excision repair pathway. CSB is very often found mutated in Cockayne syndrome, a segmental progeroid genetic disease characterized by organ degeneration and growth failure. The tumor suppressor p53 plays a pivotal role in triggering senescence and apoptosis and suppressing tumorigenesis. Although p53...
متن کاملCockayne syndrome group A and B proteins converge on transcription-linked resolution of non-B DNA.
Cockayne syndrome is a neurodegenerative accelerated aging disorder caused by mutations in the CSA or CSB genes. Although the pathogenesis of Cockayne syndrome has remained elusive, recent work implicates mitochondrial dysfunction in the disease progression. Here, we present evidence that loss of CSA or CSB in a neuroblastoma cell line converges on mitochondrial dysfunction caused by defects in...

Reciprocally regulated chromatin association of Cockayne syndrome protein B and p53 protein.
The Cockayne syndrome complementation group B (CSB) protein is an ATP-dependent chromatin remodeler with an essential function in transcription-coupled DNA repair, and mutations in the CSB gene are associated with Cockayne syndrome. The p53 tumor suppressor has been known to interact with CSB, and both proteins have been implicated in overlapping biological processes, such as DNA repair and agi...
متن کاملHuman Cockayne syndrome B protein reciprocally communicates with mitochondrial proteins and promotes transcriptional elongation
Cockayne syndrome (CS) is a rare human disorder characterized by pathologies of premature aging, neurological abnormalities, sensorineural hearing loss and cachectic dwarfism. With recent data identifying CS proteins as physical components of mitochondria, we sought to identify protein partners and roles for Cockayne syndrome group B (CSB) protein in this organelle. CSB was found to physically ...
