  • 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.

  • Anti-Lin28B antibody (ab71415) at 1/1000 dilution + K562 cell line lysates at 35 µg

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

    Predicted band size : 27 kDa
    Observed band size : 27 kDa

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

  • Immunohistochemical staining of Lin28B in Human testis tissue sections (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections) with ab71415 at a dilution of 1/25. Tissue was fixed with formaldehyde and blocked with 3% BSA for 0.5 hour at 38°C. Antigen retrieval was heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody (1/25) for 1 hour at 37°C. A HRP-conjugated goat anti-rabbit polyclonal (ready to use) was used as the secondary antibody.

  • Immunohistochemistry (Formalin/PFA-fixed parffin-embedded sections) analysis of human spleen tissue labelling Lin28B with ab71415 at 1/50. A peroxidase conjugated secondary antibody was used followed by AEC staining.

  • Immunocytochemisty/Immunofluorescence analysis of HepG2 cells labelling Lin28B (green) with ab71415. An Alexa Fluor® 488-conjugated goat anti-rabbit IgG was used as the secondary antibody. Counterstained with DAPI (blue)

  • Flow cytometry analysis of HL-60 cells labelling Lin28B (green) with ab71415 compared to a negative control (blue). A FITC-conjugated goat anti-rabbit IgG was used as the secondary antibody.
