Expression of Xeroderma Pigmentosum Group G (XPG) in Sporadic Breast Carcinoma

The founding members of xeroderma pigmentosum group G produce XPG protein with severely impaired endonuclease activity.

Of the eight human genes implicated in xeroderma pigmentosum, defects in XPG produce some of the most clinically diverse symptoms. These range from mild freckling to severe skeletal and neurologic abnormalities characteristic of Cockayne syndrome. Mildly affected xeroderma pigmentosum group G patients have diminished XPG endonuclease activity in nucleotide excision repair, whereas severely affe...

XPE ( xeroderma pigmentosum , complementation group

Xeroderma pigmentosum complementation group C protein (XPC) expression in basal cell carcinoma.

BACKGROUND The Xeroderma pigmentosum complementation group C protein (XPC) is a general sensor of damaged DNA. Individuals carrying a mutation in XPC genes exhibit marked photosensitivity and increased occurrence of skin cancers. Little is known about the distribution of XPC protein in basal cell carcinoma (BCC). AIM To determine whether the XPC protein is associated with basal cell carcinoma...

Neuroimaging features of xeroderma pigmentosum group A

Xeroderma pigmentosum group A (XPA) is a hereditary dermatological disease in which hypersensitivity to ultraviolet radiation and various neurological symptoms are observed. In this study, to evaluate the degeneration occurring in the brain of XPA patients, neurological examinations by an established neurologist and 3-Tesla magnetic resonance imaging (MRI) were performed in 10 Japanese XPA pati...

XPC ( xeroderma pigmentosum , complementation group C )

Protein Description 939 amino acids. Expression Ubiquitous. Localisation Nuclear. Function Involved in the early recognition of DNA damage present in chromatine. Two proteins have been identified and implicated in (one of) the first steps of NER, i.e. the recognition of lesions in the DNA: the XPA gene product and the XPC gene product in complex with HR23B. This XPC-HR23B complex has been impli...
