Binds primary let-7 transcripts (pri-let-7), including pri-let-7g and pri-let-7a-1, and sequester them in the nucleolus, away from the microprocessor complex, hence preventing their processing into mature miRNA (PubMed: 22118463). Does not act on pri-miR21 (PubMed: 22118463). The repression of let-7 expression is required for normal development and contributes to maintain the pluripotent state of embryonic stem cells by preventing let-7-mediated differentiation. When overexpressed, recruits ZCCHC11\/TUT4 uridylyltransferase to pre-let-7 transcripts, leading to their terminal uridylation and degradation (PubMed: 19703396). This activity might not be relevant in vivo, as LIN28B-mediated inhibition of let-7 miRNA maturation appears to be ZCCHC11-independent (PubMed: 22118463). Interaction with target pre-miRNAs occurs via an 5'-GGAG-3' motif in the pre-miRNA terminal loop. Mediates MYC-induced let-7 repression (By similarity). When overexpressed, isoform 1 stimulates growth of the breast adenocarcinoma cell line MCF-7. Isoform 2 has no effect on cell growth.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch_area\u003c\/b\u003e:Others\u003c\/p\u003e\u003cp\u003e\u003cb\u003eApplications\u003c\/b\u003e:ELISA\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTarget_protein\u003c\/b\u003e:LIN28B\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReactivity\u003c\/b\u003e:Human\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay type\u003c\/b\u003e:Sandwich\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSensitivity\u003c\/b\u003e:0.044ng\/ml\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDetection range\u003c\/b\u003e:0.1-35ng\/ml\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSample type\u003c\/b\u003e:Serum, plasma or other biological fluids\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFull product name\u003c\/b\u003e:Protein Lin-28 Homolog B\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSpecies\u003c\/b\u003e:Human\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStorage\u003c\/b\u003e:2-8ºC\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay time\u003c\/b\u003e:1h 30m\u003c\/p\u003e\u003cp\u003e\u003cb\u003eUniProt accession\u003c\/b\u003e:Q6ZN17\u003c\/p\u003e\u003cp\u003e\u003cb\u003eMASS(Da)\u003c\/b\u003e:27,084\u003c\/p\u003e\u003cp\u003e\u003cb\u003eGeneID\u003c\/b\u003e:389421\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSynonyms\u003c\/b\u003e:LIN28B;Lin-28B;Protein lin-28 homolog B\u003c\/p\u003e\u003cp\u003e\u003cb\u003eGene names\u003c\/b\u003e:LIN28B\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStandard solution\u003c\/b\u003e:40ng\/ml\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48648016756836,"sku":"E0441Hu","price":1025.92,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_87c34e1b-cd12-4ec4-bd3c-76a5b09f0c95.jpg?v=1782706070","url":"https:\/\/www.genebiosystems.com\/products\/human-protein-lin-28-homolog-b-lin28b-elisa-kit","provider":"GeneBio ","version":"1.0","type":"link"}
