靶标

  • 功能General activator of RNA polymerase which utilizes different TFIIIB complexes at structurally distinct promoters. The isoform 1 is involved in the transcription of tRNA, adenovirus VA1, 7SL and 5S RNA. Isoform 2 is required for transcription of the U6 promoter.
  • 序列相似性Belongs to the TFIIB family.
    Contains 1 TFIIB-type zinc finger.
  • 翻译后修饰Phosphorylated upon DNA damage, probably by ATM or ATR.
  • 细胞定位Nucleus.

Anti-BRF1 antibody 图像

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human prostate carcinoma tissue labelling BRF1 with ab74221 at 1/200 (1µg/ml). Detection: DAB.
  • All lanes : Anti-BRF1 antibody (ab74221) at 0.04 µg/ml

    Lane 1 : HeLa whole cell lysate at 50 µg
    Lane 2 : HeLa whole cell lysate at 15 µg
    Lane 3 : HeLa whole cell lysate at 5 µg
    Lane 4 : 293T whole cell lysate at 50 µg


    Predicted band size : 74 kDa
    Observed band size : 74 kDa
    Additional bands at : 140 kDa,200 kDa. We are unsure as to the identity of these extra bands.
  • HeLa whole cell lysate (1mg) was subjected to immunoprecipitation using ab74221 (3µg/mg lysate; lane 1) or a control IgG antibody (lane 2). 20% of the immunoprecipitates were used for Western blotting and bands were identified using ab74221 at a concentration of 1µg/ml. A band at the predicted molecular weight of 74kDa was detected using chemiluminescence with an exposure time of 3 seconds.
