ab126745 Anti-ADAR1 antibody [EPR7033] was shown to specifically react with ADAR1 in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266846 (knockout cell lysate ab257131) was used. Wild-type and ADAR1 knockout samples were subjected to SDS-PAGE. ab126745 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4° at 1 in 1000 dilution and 1 in 20000 dilution respectively.

Handling procedures

Initial handling guidelines

Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.

1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.

Subculture guidelines
  • All seeding densities should be based on cell counts gained by established methods.
  • A guide seeding density of 2x104 cells/cm2 is recommended.
  • Cells should be passaged when they have achieved 80-90% confluence.
Culture medium

DMEM (High Glucose) + 10% FBS

Cryopreservation medium

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

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.

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.
