ADAR refers to a protein target that is studied across multiple biological contexts; annotations and nomenclature can vary by species and isoform. This product corresponds to the Homo sapiens (Human) sequence context, which can be important when comparing homologs or orthologs across model systems. For curated functional annotations, domains, and sequence features, consult primary databases (e.g., UniProt\/NCBI) and the recent literature for the specific organism and isoform.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eDissecting domain-specific functions of regulatory proteins involved in chromatin organization and transcriptional control.\u003c\/li\u003e \u003cli\u003eMapping protein–protein and protein–nucleic acid interactions that coordinate gene expression programs.\u003c\/li\u003e \u003cli\u003eBuilding in vitro assays for enzymatic activities and reader–writer–eraser mechanisms linked to epigenetic regulation.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelevance:\u003c\/strong\u003e Catalyzes the hydrolytic deamination of adenosine to inosine in double-stranded RNA referred to as A-to-I RNA editing. This may affect gene expression and function in a number of ways that include mRNA translation by changing codons and hence the amino acid sequence of proteins; pre-mRNA splicing by altering splice site recognition sequences; RNA stability by changing sequences involved in nuclease recognition; genetic stability in the case of RNA virus genomes by changing sequences during viral RNA replication; and RNA structure-dependent activities such as microRNA production or targeting or protein-RNA interactions. Can edit both viral and cellular RNAs and can edit RNAs at multiple sites or at specific sites. Its cellular RNA substrates include: bladder cancer-associated protein, neurotransmitter receptors for glutamate and serotonin and GABA receptor. Site-specific RNA editing of transcripts encoding these proteins results in amino acid substitutions which consequently alters their functional activities. Exhibits low-level editing at the GRIA2 Q\/R site, but edits efficiently at the R\/G site and HOTSPOT1. Its viral RNA substrates include: hepatitis C virus, vesicular stomatitis virus, measles virus, hepatitis delta virus, and human immunodeficiency virus type 1. Exhibits either a proviral or an antiviral effect and this can be editing-dependent, editing-independent or both. Impairs HCV replication via RNA editing at multiple sites. Enhances the replication of MV, VSV and HIV-1 through an editing-independent mechanism via suppression of EIF2AK2\/PKR activation and function. Stimulates both the release and infectivity of HIV-1 viral particles by an editing-dependent mechanism where it associates with viral RNAs and edits adenosines in the 5'UTR and the Rev and Tat coding sequence. Can enhance viral replication of HDV via A-to-I editing at a site designated as amber\/W, thereby changing an UAG amber stop codon to an UIG tryptophan codon that permits synthesis of the large delta antigen which has a key role in the assembly of viral particles. However, high levels of ADAR1 inhibit HDV replication.\u003c\/p\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eAssay and standard development for immunoassays or binding-based detection methods.\u003c\/li\u003e \u003cli\u003eProtein–protein interaction studies (e.g., receptor–ligand or complex assembly) using purified components.\u003c\/li\u003e \u003cli\u003eStructure–function analysis, including domain mapping or evaluation of sequence variants.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eIn quantitative assay development, changes in binding or activity readouts are typically interpreted relative to appropriate negative\/positive controls and, where possible, orthogonal assay formats that support the same conclusion.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eRecombinant constructs may represent a defined region (domain) rather than the full-length protein; interpret results in the context of the expressed region.\u003c\/li\u003e \u003cli\u003eTag or fusion elements can aid purification and detection but may influence binding surfaces or oligomerization; consider tag controls when relevant.\u003c\/li\u003e \u003cli\u003eSpecies and isoform differences can affect interaction partners and post-translational modifications; align experimental controls to the intended biological context.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry for P55265 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P55265\/entry - NCBI Gene search (ADAR) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=ADAR - PubMed search (ADAR) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=ADAR - RCSB PDB search (ADAR) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=ADAR - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065321185645,"sku":"CSB-MP001324HU-1MG","price":2800.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065492332909,"sku":"CSB-MP001324HU-100UG","price":370.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065492365677,"sku":"CSB-MP001324HU-20UG","price":190.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-MP001324HU-SDS.jpg?v=1772476600","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-double-stranded-rna-specific-adenosine-deaminase-adar-partial-bhp10510433","provider":"BioHippo","version":"1.0","type":"link"}
