xeroderma pigmentosum/シロイヌナズナ

Plants are continuously exposed to agents that can generate DNA lesions. Nucleotide Excision Repair (NER) is one of the repair pathways employed by plants to protect their genome, including from sunlight. The Xeroderma Pigmentosum type B (XPB) protein is a DNA helicase shown to be involved in NER

The human gene XPB, defective in xeroderma pigmentosum patients complementation group B, encodes a DNA helicase involved in several DNA metabolic pathways, including DNA repair and transcription. The high conservation of this gene has allowed the cloning of homologs in various species, such as

Calmodulin-like protein 19 (CML19) is an Arabidopsis centrin that modulates nucleotide excision repair (NER) by binding to RAD4 protein, the Arabidopsis homolog of human Xeroderma pigmentosum complementation group C protein. Although the necessity of CML19 as a part of the RAD4 plant recognition

Frequent exposure of plants to solar ultraviolet radiation (UV) results in damaged DNA. One mechanism of DNA repair is the light independent pathway Global Genomic Nucleotide Excision Repair (GG-NER), which repairs UV damaged DNA throughout the genome. In mammals, GG-NER DNA damage recognition is

The xeroderma pigmentosum complementation group B (XPB) protein is involved in both DNA repair and transcription in human cells. It is a component of the transcription factor IIH (TFIIH) and is responsible for DNA helicase activity during nucleotide (nt) excision repair (NER). Its high evolutionary

The Saccharomyces cerevisiae RAD30 gene encodes a novel eukaryotic DNA polymerase, pol eta that is able to replicate across cis-syn cyclobutane pyrimidine dimers both accurately and efficiently. Very recently, a human homolog of RAD30 was identified, mutations in which result in the

In plants, exposure to solar ultraviolet (UV) light is unavoidable, resulting in DNA damage. Damaged DNA causes mutations, replication arrest, and cell death, thus efficient repair of the damaged DNA is essential. A light-independent DNA repair pathway called nucleotide excision repair (NER) is
