  • Function

    Involved in transcriptional activation and repression of select genes by chromatin remodeling (alteration of DNA-nucleosome topology). Binds DNA non-specifically. Also involved in vitamin D-coupled transcription regulation via its association with the WINAC complex, a chromatin-remodeling complex recruited by vitamin D receptor (VDR), which is required for the ligand-bound VDR-mediated transrepression of the CYP27B1 gene. Belongs to the neural progenitors-specific chromatin remodeling complex (npBAF complex) and the neuron-specific chromatin remodeling complex (nBAF complex). During neural development a switch from a stem/progenitor to a post-mitotic chromatin remodeling mechanism occurs as neurons exit the cell cycle and become committed to their adult state. The transition from proliferating neural stem/progenitor cells to post-mitotic neurons requires a switch in subunit composition of the npBAF and nBAF complexes. As neural progenitors exit mitosis and differentiate into neurons, npBAF complexes which contain ACTL6A/BAF53A and PHF10/BAF45A, are exchanged for homologous alternative ACTL6B/BAF53B and DPF1/BAF45B or DPF3/BAF45C subunits in neuron-specific complexes (nBAF). The npBAF complex is essential for the self-renewal/proliferative capacity of the multipotent neural stem cells. The nBAF complex along with CREST plays a role regulating the activity of genes essential for dendrite growth.
  • Tissue specificity

    Highly expressed in spleen, thymus, prostate, testis, ovary, small intestine, colon, and PBL, and at a much lower level in heart, brain, placenta, lung, liver, skeletal muscle, kidney, and pancreas.
  • Sequence similarities

    Contains 1 ARID domain.
  • Post-translational

    Phosphorylated upon DNA damage, probably by ATM or ATR.

  • Immunohistochemical analysis of paraffin embedded Human kidney tissue (Left image) labeling ARID1A using ab182560 at 1/1000 dilution. Right image: Right picture: paraffine embedded human clear cell carcinoma of kidney with ARID1A mutation. A Ready to use HRP Polymer for Rabbit IgG (prediluted) was used as secondary. Counterstain: Hematoxylin.

    Heat mediated antigen retrieval with Tris-EDTA, pH 9 was performed.

  • ab182560 staining ARID1A in wild-type HAP1 cells (top panel) and ARID1A knockout HAP1 cells (bottom panel). The cells were fixed with 4% formaldehyde (10min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab182560 at 1/500 dilution and ab195889 at 1/250 dilution (shown in pseudo colour red) overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Rabbit IgG (Alexa Fluor® 488) (ab150081) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

  • Flow Cytometry analysis of SH-SY5Y (human neuroblastoma) cells labeling ARID1A  with purified ab182560 at 1/230 dilution(10ug/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor® 488)(1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) were used as the unlabeled control.

  • Immunofluorescent analysis of SH-SY5Y cells labeling ARID1A with ab182560 at 1/500 and Goat anti rabbit IgG(Alexa Fluor®555) at 1/200. Image at the right stained with DAPI.

Customer reviews and Q&As


These two antibodies are extremely similar. They recognise the same protein in the same applications and species however they are different clones. The immunogen used for both antibodies is the same (aa1200-1350).

Although we have not mapped the epitopes for each of these antibodies, we have data to suggest that they have different epitopes and therefore will recognise a different sequence of amino acids within the protein. This is as far as we are aware, the only difference between these two antibodies.
