Description

LIN28A is an evolutionarily conserved RNA-binding protein that plays a pivotal role in regulating pluripotency, developmental timing, and cellular reprogramming. As one of the four Yamanaka factors capable of inducing pluripotent stem cells, LIN28A has become a focal point in stem cell biology and regenerative medicine research. Beyond its role in maintaining stemness, LIN28A dysregulation has been implicated in various malignancies, where it promotes oncogenic transformation through its inhibition of let-7 microRNA biogenesis, making it a compelling target for cancer biology studies.

This recombinant monoclonal antibody, clone 1C2, offers the reproducibility and consistency that demanding research applications require. Produced using recombinant technology with a sequence-defined approach, this antibody eliminates the lot-to-lot variability that can compromise longitudinal studies and multi-site collaborations. The rabbit host origin combined with monoclonal specificity ensures high-affinity binding to human LIN28A, providing reliable detection across your experimental workflow.

Validation studies demonstrate robust performance in flow cytometry applications using HepG2 cells, a hepatocellular carcinoma line known to express LIN28A. The clear separation between specific staining and isotype control signals confirms the antibody's specificity for intracellular detection of this RNA-binding protein. Researchers can confidently employ this antibody at dilutions ranging from 1:50 to 1:200 for flow cytometry, with additional utility in ELISA-based quantification studies.

Whether investigating the molecular mechanisms of pluripotency maintenance, exploring LIN28A's oncogenic functions in cancer models, or developing cell-based assays for drug discovery, this antibody provides a dependable tool for advancing your understanding of this critical developmental regulator.

Target Background

Function

RNA-binding protein that inhibits processing of pre-let-7 miRNAs and regulates translation of mRNAs that control developmental timing, pluripotency and metabolism. Seems to recognize a common structural G-quartet (G4) feature in its miRNA and mRNA targets (Probable). 'Translational enhancer' that drives specific mRNAs to polysomes and increases 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 mRNA stabilization. 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. Suppressor of microRNA (miRNA) biogenesis, including that of let-7, miR107, miR-143 and miR-200c. Specifically binds the miRNA precursors (pre-miRNAs), recognizing an 5'-GGAG-3' motif found in pre-miRNA terminal loop, and recruits TUT4 AND tut7 uridylyltransferaseS. This results in the terminal uridylation of target pre-miRNAs. Uridylated pre-miRNAs fail to be processed by Dicer and undergo degradation. The repression of let-7 expression is required for normal development and contributes to maintain the pluripotent state by preventing let-7-mediated differentiation of embryonic stem cells. Localized to the periendoplasmic reticulum area, binds to a large number of spliced mRNAs and inhibits the translation of mRNAs destined for the ER, reducing the synthesis of transmembrane proteins, ER or Golgi lumen proteins, and secretory proteins. Binds to and enhances the translation of mRNAs for several metabolic enzymes, such as PFKP, PDHA1 or SDHA, increasing glycolysis and oxidative phosphorylation. Which, with the let-7 repression may enhance tissue repair in adult tissue.
