Protocol Available protocols: Western Blotting, Immunoprecipitation Specificity / Sensitivity TAF-I beta (F9P9J) Rabbit Monoclonal Antibody recognizes endogenous levels of total TAF-Iβ protein. This antibody does not cross-react with TAF-Iα protein. Species Reactivity: Human, Rat, Monkey Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding His17 of human TAF-Iβ protein. Background Templated activating factor I (TAF-I), also known as SET, is a histone chaperone protein first discovered to play a role in adenovirus chromatin replication (1,2). TAF-I is an acidic protein capable of binding histone cores and remodeling nucleosomes (3). TAF-I is part of the inhibitor of acetyltransferases (INHAT) complex, which sharply represses histone acetylation by PCAF and P300/CBP (4). INHAT complex binding to histone tails is affected by certain histone marks (5). TAF-I has two predominant isoforms, TAF-Iα and TAF-Iβ, which only differ in the N-terminus. TAF-Iα is the predominant isoform in embryonic stem cells, and its expression is regulated by pluripotent factors. Upon differentiation, an isoform shift takes place as the alternative promoter is upregulated, generating TAF-Iβ (6-8). TAF-I uniquely exhibits histone chaperone activity toward linker histone H1, regulating higher-order chromatin structure. TAF-Iα has less activity than TAF-Iβ due to its inhibitory interaction between its unique N-terminus and the C-terminus (9,10). TAF-I has been implicated in oncogenic transformation by inhibiting apoptosis (11).
