Function

Catalyzes the hydrolytic deamination of adenosine to inosine in double-stranded RNA (dsRNA) referred to as A-to-I RNA editing (PubMed:12618436, PubMed:7565688, PubMed:7972084). 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 since the translational machinery read the inosine as a guanosine; 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 (hyper-editing) or at specific sites (site-specific editing). Its cellular RNA substrates include: bladder cancer-associated protein (BLCAP), neurotransmitter receptors for glutamate (GRIA2) and serotonin (HTR2C) and GABA receptor (GABRA3). 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 (HCV), vesicular stomatitis virus (VSV), measles virus (MV), hepatitis delta virus (HDV), and human immunodeficiency virus type 1 (HIV-1). Exhibits either a proviral (HDV, MV, VSV and HIV-1) or an antiviral effect (HCV) and this can be editing-dependent (HDV and HCV), editing-independent (VSV and MV) or both (HIV-1). 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 (W) codon that permits synthesis of the large delta antigen (L-HDAg) which has a key role in the assembly of viral particles. However, high levels of ADAR1 inhibit HDV replication.

Notes

Human ADAR1 Antibody Pair - BSA and Azide free (ab302749) is a matched pair of unconjugated recombinant rabbit monoclonal capture and detection antibodies used to quantify Human ADAR1 in sandwich ELISAs and many other pair-based applications.

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

The pair can be used in variety of assays and platforms including but not limited to:

  • Sandwich ELISA
  • FRET/TR-FRET/HTRF
  • Meso Scale Discovery® (MSD®)
  • Bead-based assays
  • AlphaLISA®/AlphaScreen®
  • DELFIA® immunoassays
  • Simoa® and Single Molecule Counting (SMC™) immunoassays
  • Multiplex

Our antibody pairs are supplied in a carrier-free format that is conjugation-ready:

  • Buffer free of BSA, sodium azide, and glycerol for higher conjugation efficiency.
  • Concentration of ~1 mg/ml as measured by the protein A280 method.

We can label antibodies for you: get in touch today to discuss how we can help accelerate your assay development with custom conjugation services.

Pairs are screened in biological samples, including plasma and serum, to ensure specificity in complex samples.

Please note:

The recommended antibody orientation is based on internal optimization in sandwich ELISA. Antibody orientation is assay dependent and needs to be optimized for each assay type.

The range provided for this antibody pair is based on initial sandwich ELISA validation data using recombinant protein. Performance and range of the antibody pair will depend on the specific characteristics of your assay, including standard protein selection.

We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibodies in other assays.

Antibody properties:

Capture antibody: recombinant rabbit monoclonal (unconjugated) – 100 µg

Detector antibody: recombinant rabbit monoclonal (unconjugated) - 100 µg

Concentration: ~1 mg/ml

Activity summary

ADAR1 also known as RNA-specific adenosine deaminase 1 or ADAR is an enzyme with a mass of approximately 150 kDa. This protein targets double-stranded RNA (dsRNA) and acts mechanistically to convert adenosine to inosine in pre-mRNA sequences a process known as A-to-I RNA editing. ADAR1 is expressed in numerous tissues with high levels in the brain liver and lungs. Its localization within cells can vary often found in both the nucleus and cytoplasm which influences its function.

Biological function summary

ADAR1 plays a role in the regulation of RNA molecules affecting their stability and translation. It is linked to the editosome complex working alongside other proteins to perform RNA editing tasks. By modifying the coding potential of mRNAs ADAR1 contributes to the diversity of proteomes and helps manage the responses to viral RNAs giving the immune system tools to recognize endogenous and exogenous RNA.

Pathways

ADAR1 is significant in the interferon signaling pathway and RNA processing pathways. It operates in coordination with proteins like PKR which is involved in the response to viral infections. ADAR1 ensures that the immune response is not directed against the self highlighting its role in the regulation of the innate immune system. These pathways are critical in maintaining homeostasis and preventing unchecked immune responses.

Associated diseases and disorders

Mutations or dysregulation of ADAR1 have associations with autoimmune diseases like Aicardi-Goutieres syndrome and certain cancers. The enzyme's role in editing RNA makes it essential in preventing inappropriate immune attacks against the body's own cells highlighting its interaction with MDA5 another protein involved in immune regulation. Understanding ADAR1 and its related pathways may offer potential therapeutic targets for these conditions including exploration into ADAR1 inhibitors as interventions.
