    Product Usage Information

    For optimal ChIP results, use 10 μL of antibody and 10 μg of chromatin (approximately 4 × 106 cells) per IP. This antibody has been validated using SimpleChIP® Enzymatic Chromatin IP Kits.
    Application Dilution
    Chromatin IP 1:50

    Storage

    Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

    Protocol

    Specificity / Sensitivity

    TFII-I (E9U2N) Rabbit mAb (ChIP Formulated) recognizes endogenous levels of total TFII-I protein.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val263 of human TFII-I protein.

    Background

    TFII-I (also known as SPIN and BAP-135) is a multifunctional transcription factor that facilitates basal transcriptional machinery assembly at the core promotor region, as well as the assembly of the transcriptional activator complex at upstream regulatory sites (1). Four isoforms of TFII-I (alpha, beta, gamma, and delta) form homo- or heteromeric complexes, which may perform different functions on different promoters (1). In B cells, cross-linking of BCR (B cell receptors) leads to TFII-I phosphorylation at Tyr248 by Btk (2). This phosphorylation disrupts the association of Btk and TFII-I and enhances TFII-I transcriptional activity and nuclear localization (2). In nonlymphoid cells, TFII-I is phosphorylated at Tyr248 by Src dependent kinase or JAK2 (3,4). PKG (cGMP-dependent kinase) interacts with and phosphorylates TFII-I at Ser371 and 743, which also promotes TFII-I transcription activity (5). TFII-I activity is also modulated by HDAC3 (Histone Deacetylase 3) through a physical interaction between the two proteins (6).
