ICC/IF 1/100 - 1/250.


  • Function
    Binds to the 5'-UTR of the insulin-like growth factor 2 (IGF2) mRNAs. Binding is isoform-specific. May regulate translation of target mRNAs.
  • Tissue specificity
    Expressed in oocytes, granulosa cells of small and growing follicles, Leydig cells, spermatogonia and semen (at protein level). Expressed in testicular cancer (at protein level). Expressed weakly in heart, placenta, skeletal muscle, bone marrow, colon, kidney, salivary glands, testis and pancreas. Detected in fetal liver, fetal ovary, gonocytes and interstitial cells of the testis.
  • Sequence similarities
    Belongs to the RRM IMP/VICKZ family.
    Contains 4 KH domains.
    Contains 2 RRM (RNA recognition motif) domains.
  • Domain
    The third and fourth KH domains are important for binding to the untranslated region (UTR) of target mRNA.
  • Cellular localization
    Cytoplasm. Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Localizes at the connecting piece and the tail of the spermatozoa.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human lung carcinoma tissue sections labeling IGF2BP2 with purified ab124930 at 1/200 dilution (4.8 μg/ml). Heat mediated antigen retrieval was performed using EDTA Buffer, PH9. Hematoxylin was used to counter stain. ImmunoHistoProbe one step HRP Polymer (ready to use) was used as the secondary antibody at 1/0 dilution. PBS instead of the primary antibody was used as the negative control.

  • Immunocytochemistry/ Immunofluorescence analysis of HepG2 (Human liver hepatocellular carcinoma cell line) cells labeling IGF2BP2 with purified ab124930 at 1/250 dilution (3.8μg/ml). Cells were fixed in 4% paraformaldehyde and permeabilized with 0.1% tritonX-100. Cells were counterstained with ab195889, an anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) at 1/200 (2.5 μg/ml). ab150077, a Goat anti-rabbit IgG (Alexa Fluor® 488) was used as the secondary antibody at 1/1000 dilution. DAPI nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.
