Descripción

General description

XPB (Xeroderma pigmentosum complementation group B) is located on the human chromosome at 2q14.3. TFIIH (General transcription and DNA repair factor IIH helicase) consists of nine protein subunits, XPB (ERCC3) being one of them. It is an ATP-dependent DNA helicase of 89 kDa. The XPB is localized in the neurons.

Immunogen

synthetic peptide corresponding to amino acids 765-782 of human XPB, also known as ERCC3, conjugated to KLH via an N-terminal added cysteine residue. The immunizing peptide differs from the mouse and rat sequences in one and three amino acids respectively.

Application

Anti-XPB antibody has been used in immunoblotting andimmunofluorescence.

Biochem/physiol Actions

XPB (General transcription and DNA repair factor IIH helicase subunit XPB) is involved in DNA repair and transcription. Phosphorylation on Ser⁷⁵¹ of XPB inhibits TFIIH repair activity, leaving its transcription function intact. Mutations in the gene encoding XPB causes Xeroderma Pigmentosum, Cockayne′s syndrome, and trichothiodystrophy.

Physical form

Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide.
