Application Abreviews Notes
IHC-P 1/100 - 1/500. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
WB 1/2000 - 1/10000. Detects a band of approximately 120 kDa (predicted molecular weight: 97 kDa).
IP Use at 2-5 µg/mg of lysate.


  • Function
    Catalyzes the 2 serial methylation steps for the conversion of the 7-monomethylguanosine (m(7)G) caps of snRNAs and snoRNAs to a 2,2,7-trimethylguanosine (m(2,2,7)G) cap structure. The enzyme is specific for guanine, and N7 methylation must precede N2 methylation. Hypermethylation of the m7G cap of U snRNAs leads to their concentration in nuclear foci, their colocalization with coilin and the formation of canonical Cajal bodies (CBs). Plays a role in transcriptional regulation.
  • Tissue specificity
    Ubiquitously expressed. High expression in heart, skeletal muscle, kidney, liver and placenta.
  • Sequence similarities
    Belongs to the methyltransferase superfamily. Trimethylguanosine synthase family.
  • Cellular localization
    Cytoplasm. Nucleus > Cajal body. A 90 kDa isoform is found in the nucleus while a 55 kDa isoform is found in the cytoplasm and colocalizes with the tubulin network.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human colon carcinoma tissue labelling PIMT with ab70559 at 1/200 (1µg/ml). Detection: DAB.
  • All lanes : Anti-PIMT antibody (ab70559) 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 : 97 kDa
    Observed band size : 120 kDa (why is the actual band size different from the predicted?)
    There are multiple additional bands. We are unsure as to the identity of these extra bands.
  • Detection of Human PIMT by Immunoprecipitation in Whole cell lysate from HeLa cells (1 mg for IP, 20% of IP loaded), using ab70559 at 3 µg/mg lysate for IP and at 1 µg/ml for subsequent Western blot detection.
