Product nameHuman ADAR (ADAR1) knockout HEK293T cell lysate
Knockout cell lysate achieved by CRISPR/Cas9.
Parental Cell LineHEK293T
Mutation descriptionKnockout achieved by using CRISPR/Cas9, 17 bp deletion in exon2 and 1 bp insertion in exon2.
Knockout validationSanger Sequencing, Western Blot (WB)
Reconstitution notesTo use as WB control, resuspend the lyophilizate in 50 µL of LDS* Sample Buffer to have a final concentration of 2 mg/ml. For reducing conditions, we recommend a final concentration of 0.1 M DTT.
*Usage of SDS sample buffer is not recommended with these lyophilized lysates.
Lysate preparation: Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10). This means that the protein of interest is denatured. If you require a native form of the protein please use the live cell version - found here. Please refer to our lysis protocol for further details on how our lysates are prepared.
User storage instructions: After reconstitution, store the lysate at -80°C.
Access thousands of knockout cell lysates, generated from commonly used cancer cell lines.

FunctionConverts multiple adenosines to inosines and creates I/U mismatched base pairs in double-helical RNA substrates without apparent sequence specificity. Has been found to modify more frequently adenosines in AU-rich regions, probably due to the relative ease of melting A/U base pairs as compared to G/C pairs. Functions to modify viral RNA genomes and may be responsible for hypermutation of certain negative-stranded viruses. Edits the messenger RNAs for glutamate receptor (GLUR) subunits by site-selective adenosine deamination. Produces low-level editing at the GLUR-B Q/R site, but edits efficiently at the R/G site and HOTSPOT1. Binds to short interfering RNAs (siRNA) without editing them and suppresses siRNA-mediated RNA interference. Binds to ILF3/NF90 and up-regulates ILF3-mediated gene expression.
Tissue specificityUbiquitously expressed, highest levels were found in brain and lung.
Involvement in diseaseDefects in ADAR are a cause of dyschromatosis symmetrical hereditaria (DSH) [MIM:127400]; also known as reticulate acropigmentation of Dohi. DSH is a pigmentary genodermatosis of autosomal dominant inheritance characterized by a mixture of hyperpigmented and hypopigmented macules distributed on the dorsal parts of the hands and feet.
Sequence similaritiesContains 1 A to I editase domain.
Contains 2 DRADA repeats.
Contains 3 DRBM (double-stranded RNA-binding) domains.
modificationsSumoylation reduces RNA-editing activity.
Cellular localizationCytoplasm. Nucleus > nucleolus. Isoform 1 is found predominantly in cytoplasm but appears to shuttle between the cytoplasm and nucleus. Isoform 5 is found exclusively in the nucleolus.

ab126745 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 4oC at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.
