Background Information

TAF1, also named as BA2R, CCG1, CCGS, TAF2A, p250, Cell cycle gene 1 protein, TAFII250 and DYT3, belongs to the TAF1 family. TAF1 is the largest component and core scaffold of the TFIID basal transcription factor complex. It contains novel N- and C-terminal Ser/Thr kinase domains which can autophosphorylate or transphosphorylate other transcription factors. TAF1 phosphorylates TP53 on 'Thr-55' which leads to MDM2-mediated degradation of TP53. TAF1 phosphorylates GTF2A1 and GTF2F1 on Ser residues. It possesses DNA-binding activity. It is essential for progression of the G1 phase of the cell cycle. Defects in TAF1 are the cause of dystonia type 3 (DYT3) which also called X-linked dystonia-parkinsonism (XDP). The antibody is specific to TAF1. It has several isoforms with predicted MW's of 200-250 kDa and 170-180 kDa, it also could get about 50 kDa band which is caused by the lysate preparation.
