Target

  • Function
    Acts as a 'translational enhancer', driving specific mRNAs to polysomes and thus increasing the efficiency of protein synthesis. Its association with the translational machinery and target mRNAs results in an increased number of initiation events per molecule of mRNA and, indirectly, in stabilizing the mRNAs. Binds IGF2 mRNA, MYOD1 mRNA, ARBP/36B4 ribosomal protein mRNA and its own mRNA. Essential for skeletal muscle differentiation program through the translational up-regulation of IGF2 expression (By similarity). Acts 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. Degradation of pre-let-7 in embryonic stem (ES) cells contributes to the maintenance of ES cells. In contrast, LIN28A down-regulation in neural stem cells by miR-125, allows the processing of pre-let-7. 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.
  • Tissue specificity
    Expressed in embryonic stem cells (ES cells), placenta and testis.
  • Sequence similarities
    Belongs to the lin-28 family.
    Contains 2 CCHC-type zinc fingers.
    Contains 1 CSD (cold-shock) domain.
  • Developmental stage
    Expressed in fetal liver. Expression decreases during differentiation of ES cells or upon induction of neuronal differentiation by retinoic acid.
  • Domain
    The CSD domain is required for function in muscle differentiation.
  • Cellular localization
    Cytoplasm. Nucleus > nucleolus. Nucleolar localization observed in 10-15% of the nuclei in differentiated myotubes (By similarity). Shuttles between the cytoplasm and the nucleus. Localizes to cytoplasmic processing bodies and stress granules.

    Predicted band size : 23 kDa
    Observed band size : 29 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 22 kDa. We are unsure as to the identity of these extra bands.It is unclear why lin28 runs at a larger size than its predicted moleular weight but recombinant lin28 protein is also known to run at around 30 kDa.
  • Human Embryonic stem cells were fixed in PFA and then incubated with the primary antibody ab46020 (1:1000) diluted in 2% BSA for 16 hours at 4C. Cells where then washed and incubated with a Cy3 conjugated goat anti-rabbit polyclonal antibody (1:400). Cells where then washed and visualised.
  • ab46020 staining Lin28 in paraffin-embedded human tissue sections (ESC-derived embryoid bodies) by IHC-P. Tissue was fixed with paraformaldehyde and blocked with 8% Serum treatment in automated Bond Max system for 15 minutes. Samples were incubated with primary antibody (1/2000) for 15 minutes. An HRP-conjugated goat anti rabbit polyclonal (1/200) was used as secondary antibody.
