General description
Lin28 is a developmentally regulated RNA binding protein (RBP). Its down regulation is mediated in part by Lin4 and miR-125b, the mammalian micro-RNA homolog of Lin4. It is known to be negatively regulated by retinoic acid and act as a translational enhancer by driving specific mRNAs to polysomes and thus increasing the efficiency of protein synthesis by increasing the number of initiation events per mRNA molecule. Lin28 is necessary and sufficient for selectively blocking the cleavage processing of pri-let-7 miRNAs in embryonic cells (Viswanathan, 2008). Lin28 is a negative regulator of miRNA biogenesis and may play a role in blocking miRNA-mediated differentiation in stem cells and in certain cancers (Viswanathan, 2008). The mechanism by which miR-125b represses Lin28 in mammalian cells appears to involve reductions not only in translational efficiency, but also in mRNA abundance (Wu, 2005). Lin28 has shown to be essential for skeletal muscle differentiation through the translational upregulation of IGF2 expression. It is known to be expressed in testis, placenta, and embryonic stem (ES) cells.

Vertebrate genomes each encode hundreds of micro-RNAs (miRNAs), yet for few of these miRNAs is there empirical evidence as to which mRNA(s) they regulate. Here we report the identification of human lin-28 mRNA as a regulatory target of human miR-125b

Micro-RNAs are small non-coding RNAs that regulate target gene expression post-transcriptionally through base pairing with the target messenger RNA. Functional characterization of micro-RNAs awaits robust experimental methods to knock-down a micro-RNA as well as to assay its function in vivo.

MicroRNAs (miRNAs) play critical roles in development, and dysregulation of miRNA expression has been observed in human malignancies. Recent evidence suggests that the processing of several primary miRNA transcripts (pri-miRNAs) is blocked posttranscriptionally in embryonic stem cells, embryonal carcinoma cells

As part of their normal life cycle, most RNA molecules associate with several proteins that direct their fate and regulate their function. Here, we describe a novel method for identifying proteins that associate with a target RNA. The procedure is
