XPC (xeroderma pigmentosum, complementation group C)

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...

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...

ERCC 4 ( xeroderma pigmentosum , complementation group F )

Xeroderma pigmentosum group F complementing factor; DNA-repair protein complementing XPF cells 905 amino acids; form a stable complex with the ERCC1 protein; The XPF protein and the ERCC1 protein form a complex that exhibits structure specific endonuclease activity that is responsible for the 5' incision during the NER reaction. XPF-ERCC1 also binds to XPA (through ERCC1) and to RPA (through XP...

XPA ( xeroderma pigmentosum , complementation group A )

Initiates DNA repair by binding to damaged sites with various affinities, depending upon the chemical structure of the lesion. Two proteins have been identified and implicated in (one of) the first steps of Nucleotide Excision Repair (NER), i.e. the recognition of lesions in the DNA: the XPA gene product and the XPC gene product. Cells from XPA patients are extremely sensitive to UV and have ve...
