Target

  • FunctionActs as a suppressor of microRNA (miRNA) biogenesis by specifically binding the precursor let-7 (pre-let-7), a miRNA precursor. Acts by binding pre-let-7 and recruiting ZCCHC11/TUT4 uridylyltransferase, leading to the terminal uridylation of pre-let-7. Uridylated pre-let-7 miRNAs fail to be processed by Dicer and undergo degradation. Specifically recognizes the 5'-GGAG-3' motif in the terminal loop of pre-let-7. Also recognizes and binds non pre-let-7 pre-miRNAs that contain the 5'-GGAG-3' motif in the terminal loop, leading to their terminal uridylation and subsequent degradation. Mediates MYC-mediated let-7 repression. Isoform 1, when overexpressed, stimulates growth of the breast adenocarcinoma cell line MCF-7. Isoform 2 has no effect on cell growth.
  • Tissue specificityHigh expression in testis, fetal liver, placenta and in hepatocellular carcinoma (HCC). Isoform 1 is only detected in moderately and poorly differentiated HCC tissues and placenta (at protein level). Isoform 2 is detected in fetal liver, non-tumor liver tissues, as well as well-differentiated tumor tissues (at protein level).
  • Sequence similaritiesBelongs to the lin-28 family.
    Contains 2 CCHC-type zinc fingers.
    Contains 1 CSD (cold-shock) domain.
  • Cellular localizationCytoplasm. Nucleus. Predominantly cytoplasmic at G1 phase, accumulates in the nucleus in S and G2 phases. The frequency of nuclear localization in S and in G2 phases is 60% and 30%, respectively.

  • Immunohistochemistry Image of Human Testis (formalin-fixed, paraffin-embedded) stained with Lin28B antibody (ab115698) at 10 µg/ml followed by biotinylated goat anti-rabbit IgG secondary antibody, alkaline phosphatase-streptavidin and chromogen.
  • Anti-Lin28B antibody (ab115698) at 1/1000 dilution + HL60 cell line lysate at 35 µg

    Secondary
    HRP goat anti-rabbit (H+L) at 1/5000 dilution

    Predicted band size : 27 kDa

    Incubation time was overnight at 4°C. Blocking/Dilution buffer: 5% NFDM/TBST.

  • Overlay histogram showing HL-60 cells stained with ab115698 (green line). The cells were fixed with paraformaldehyde and then permeabilized with 90% methanol for 10 min. The cells were then incubated in 3% BSA to block non-specific protein-protein interactions followed by the antibody (ab115698, 1µg/1x106 cells) for 60 min at 37ºC. The secondary antibody used was FITC conjugated goat anti-rabbit IgG at 1/200 dilution for 40 min at room temperature. Blank control (blue line) was used under the same conditions. Acquisition of  >10,000 events was performed.
