Binds various RNAs, such as rRNAs, snoRNAs, 7SK and, at lower extent, mRNAs(PubMed:25470060). In the nucleolus, localizes to rDNA locus, where it directly binds rRNAs and snoRNAs, and promotes rRNA transcription, processing and modification. Required for rRNA 2'-O-methylation, possibly by promoting the recruitment of late-acting snoRNAs SNORD56 and SNORD58 with pre-ribosomal complexes(PubMed:25470060, PubMed:25477391). In the nucleoplasm, binds 7SK RNA and is recruited to the promoters of Pol II-transcribed genes: acts by facilitating the release of P-TEFb from inhibitory 7SK snRNP in a manner that is dependent on its helicase activity, thereby promoting transcription of its target genes(PubMed:25470060). Functions as cofactor for JUN-activated transcription: required for phosphorylation of JUN at 'Ser-77'(PubMed:11823437, PubMed:25260534). Can unwind double-stranded RNA(helicase) and can fold or introduce a secondary structure to a single-stranded RNA(foldase)(PubMed:9461305). Involved in rRNA processing(PubMed:14559904, PubMed:18180292).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIMMUNOGEN INFORMATION\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImmunogen\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDEAD(Asp-Glu-Ala-Asp) box polypeptide 21\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eObserved MW\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e87 kDa\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAPPLICATION\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTested Application\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eELISA, WB, IHC, IF, IP\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Dilution\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWB: 1:500-1:2000; IP: 1:200-1:1000; IHC: 1:20-1:200; IF: 1:20-1:200\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUNIPROT INFORMATION\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUniProt ID\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"http:\/\/www.uniprot.org\/uniprot\/Q9NR30\"\u003eQ9NR30\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIMAGES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cfigure class=\"w-full md:w-2\/3 p-2 border relative\"\u003e\u003cimg class=\"mx-auto\" alt=\"\" src=\"https:\/\/www.fn-test.com\/content\/uploads\/product\/images\/antibody\/image1\/FNab02299.jpg\"\u003e\u003c\/figure\u003e\n\u003cdiv class=\"w-full md:pl-8 pt-4 md:pt-0 md:w-1\/3\"\u003eImmunohistochemistry of paraffin-embedded human colon cancer using FNab02299(DDX21 antibody) at dilution of 1:100\u003c\/div\u003e\n\u003cfigure class=\"w-full md:w-2\/3 p-2 border relative\"\u003e\u003cimg class=\"mx-auto\" alt=\"\" src=\"https:\/\/www.fn-test.com\/content\/uploads\/product\/images\/antibody\/image3\/FNab02299.jpg\"\u003e\u003c\/figure\u003e\n\u003cdiv class=\"w-full md:pl-8 pt-4 md:pt-0 md:w-1\/3\"\u003eIP Result of anti-DDX21 (IP:FNab02299, 4ug; Detection:FNab02299 1:1000) with COLO 320 cells lysate 2800ug.\u003c\/div\u003e\n\u003cfigure class=\"w-full md:w-2\/3 p-2 border relative\"\u003e\u003cimg class=\"mx-auto\" alt=\"\" src=\"https:\/\/www.fn-test.com\/content\/uploads\/product\/images\/antibody\/image4\/FNab02299.jpg\"\u003e\u003c\/figure\u003e\n\u003cdiv class=\"w-full md:pl-8 pt-4 md:pt-0 md:w-1\/3\"\u003eHepG2 cells were subjected to SDS PAGE followed by western blot with FNab02299(DDX21 antibody) at dilution of 1:2000\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"FineTest","offers":[{"title":"100µg","offer_id":47561980870936,"sku":"FNab02299","price":310.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/fine_test_logo_d071ed45-420f-4967-998f-f1c1dd9aca98.jpg?v=1705893284","url":"https:\/\/danabiosci.com\/products\/new-product-607711","provider":"Dana Bioscience","version":"1.0","type":"link"}
