  • IF - GTF2I Antibody (C-term) AP6881b
    Fluorescent image of Hela cells stained with GTF2I Antibody (C-term)(Cat#AP6881b). AP6881b was diluted at 1:25 dilution. An Alexa Fluor 488-conjugated goat anti-rabbit lgG at 1:400 dilution was used as the secondary antibody (green). Cytoplasmic actin was counterstained with Alexa Fluor® 555 conjugated with Phalloidin (red).
  • WB - GTF2I Antibody (C-term) AP6881b
    Western blot analysis of lysates from A431, Hela cell line (from left to right), using GTF2I Antibody (C-term)(Cat. #AP6881b). AP6881b was diluted at 1:1000 at each lane. A goat anti-rabbit IgG H&L(HRP) at 1:5000 dilution was used as the secondary antibody. Lysates at 35ug per lane.
  • WB - GTF2I Antibody (C-term) AP6881b
    Western blot analysis of lysate from Hela cell line, using GTF2I Antibody (C-term)(Cat. #AP6881b). AP6881b was diluted at 1:1000. A goat anti-rabbit IgG H&L(HRP) at 1:5000 dilution was used as the secondary antibody. Lysate at 35ug.
  • IF - GTF2I Antibody (C-term) AP6881b
    Fluorescent image of A549 cell stained with GTF2I Antibody (C-term)(Cat#AP6881b/SA091106AV).A549 cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.1%, 10 min), then incubated with GTF2I primary antibody (1:25, 1 h at 37℃). For secondary antibody, Alexa Fluor® 488 conjugated donkey anti-rabbit antibody (green) was used (1:400, 50 min at 37℃).Cytoplasmic actin was counterstained with Alexa Fluor® 555 (red) conjugated Phalloidin (7units/ml, 1 h at 37℃).GTF2I immunoreactivity is localized to Nucleus significantly.
  • IHC-P - GTF2I Antibody (C-term) AP6881b
    Formalin-fixed and paraffin-embedded human brain tissue reacted with GTF2I Antibody (C-term), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.
  • FC - GTF2I Antibody (C-term) AP6881b
    GTF2I Antibody (C-term) (Cat. #AP6881b) flow cytometric analysis of k562 cells (bottom histogram) compared to a negative control cell (top histogram).FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.

Protein Information
Name GTF2I
Synonyms BAP135, WBSCR6
Function Interacts with the basal transcription machinery by coordinating the formation of a multiprotein complex at the C-FOS promoter, and linking specific signal responsive activator complexes. Promotes the formation of stable high-order complexes of SRF and PHOX1 and interacts cooperatively with PHOX1 to promote serum-inducible transcription of a reporter gene deriven by the C- FOS serum response element (SRE). Acts as a coregulator for USF1 by binding independently two promoter elements, a pyrimidine-rich initiator (Inr) and an upstream E-box. Required for the formation of functional ARID3A DNA-binding complexes and for activation of immunoglobulin heavy-chain transcription upon B-lymphocyte activation.
Cellular Location Cytoplasm. Nucleus {ECO:0000255|PROSITE-ProRule:PRU00484, ECO:0000269|PubMed:10373551}. Note=Colocalizes with BTK in the cytoplasm
Tissue Location Ubiquitous. Isoform 1 is strongly expressed in fetal brain, weakly in adult brain, muscle, and lymphoblasts and is almost undetectable in other adult tissues, while the other isoforms are equally expressed in all adult tissues

GTF2I is a multifunctional phosphoprotein with roles in transcription and signal transduction. It is deleted in Williams-Beuren syndrome, a multisystem developmental disorder caused by the deletion of contiguous genes at chromosome 7q11.23.
