We also show by microarray analysis that expression of the fusion protein alone in csb-null uv-sensitive syndrome (uvss) cells induces an interferon-like response that resembles both the innate antiviral response and the prolonged interferon response normally maintained by unphosphorylated stat1 (u-stat1); moreover, as might be expected based.
In addition to ercc6 (csb) and the ercc8 (csa) ubiquitin ligase complex, several other proteins and protein complexes are loaded onto stalled rna polymerase ii (rna pol ii) at dna damage sites to form a pre-incision complex that operates in the transcription-coupled nucleotide excision repair (tc-ner).
Uv-sensitive syndrome (uv s s) uv-sensitive syndrome (uv s s) was first described by itoh and colleagues [34] individuals with uv s s are sun-sensitive and they present pigmentation anomalies in sun-exposed areas of the skin; however, just as with cs, no tumors have yet been reported in their skin or internal organs.
In addition, the rare hereditary disease bloom syndrome also somehow is involved with dna ligase deficiency (although the bloom syndrome protein is a dna helicase); patients' cultured cells have high levels of chromosome aberrations and spontaneous mutation.
Mutations in uvssa cause uv-sensitive syndrome and impair rna polymerase iio processing in transcription-coupled nucleotide-excision repair.
Otud4 nominally encodes a k48-specific deubiquitinase previously shown to counteract proteasomal degradation of dna repair proteins. Demonstrate that otud4 is phosphorylated near its catalytic domain, activating a dormant k63-specific deubiquitinase activity. This enzymatic activity is shown to modulate tlr-dependent signaling by targeting the scaffolding protein myd88.

Schwertman p, lagarou a, dekkers dh et al (2012) uv-sensitive syndrome protein uvssa recruits usp7 to regulate transcription-coupled repair.
Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. Hypoxia may be classified as either generalized, affecting the whole body, or local, affecting a region of the body.
The clinical entities discussed are cerebro-oculo-facio-skeletal (cofs) syndrome, uv-sensitive syndrome, and transcription syndromes. The biochemical and clinical consequences of different mutations in a single gene are often unpredictable and can produce different clinical phenotypes.
The global health-threatening crisis from the covid-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (sars-cov-2), highlights the scientific and engineering potentials of applying ultraviolet (uv) disinfection technologies for biocontaminated air and surfaces as the major media for disease transmission. Nowadays, various environmental public settings worldwide, from.
Some conditions that involve eye damage or vision damage can be reversed while others can't. The lens focuses rays of light onto your retina, which is the light-sensitive nerve tissue that contains photosensitive computer visi.
Mounting evidence suggests that dna damage plays a central role in aging. Multiple tiers of defense have evolved to reduce the accumulation of dna damage, including reducing damaging molecules, repairing dna damage, and inducing senescence or apoptosis in response to persistent dna damage. Mutations in or failure of these pathways can lead to accelerated or premature aging and age-related.
