  • Function

    Core histone-binding subunit that may target chromatin remodeling factors, histone acetyltransferases and histone deacetylases to their histone substrates in a manner that is regulated by nucleosomal DNA. Component of several complexes which regulate chromatin metabolism. These include the type B histone acetyltransferase (HAT) complex, which is required for chromatin assembly following DNA replication; the core histone deacetylase (HDAC) complex, which promotes histone deacetylation and consequent transcriptional repression; the nucleosome remodeling and histone deacetylase complex (the NuRD complex), which promotes transcriptional repression by histone deacetylation and nucleosome remodeling; and the PRC2/EED-EZH2 complex, which promotes repression of homeotic genes during development; and the NURF (nucleosome remodeling factor) complex.
  • Sequence similarities

    Belongs to the WD repeat RBAP46/RBAP48/MSI1 family.
    Contains 7 WD repeats.

Thank you very much for your interest in ab488. I am not sure whether you are interested in receiving more information about our testing program or if you are ready to receive the discount code, so I am sending all of the information about the program just in case you are still deciding.
Since ab488 has not been tested with chicken samples, I can offer a discount off a future purchase if you buy this antibody now, test it in chicken and submit feedback to us in the form of an Abreview. It doesn’t matter whether the Abreview is positive or negative, we would just really like to receive your feedback. The discount would be to the value of 1 free primary antibody.
If you are interested in this offer, please follow these steps:
1. Reply to this e-mail to let me know that you would like to proceed and test this antibody. I will then send a discount code.
2. Purchase ab488 either by phone, fax, or online (www.abcam.com).
3. Test it in chicken.
4. Let us know the results, positive or negative, using our Abreview system (this will take about 10 minutes and images are great if you have them!). To find out how to submit an Abreview, please visit: https://www.abcam.com/abreviews.
5. After the review is submitted to us, the discount code becomes active. Simply place your new order by phone, fax, or on the web and mention the discount code. The discount can be redeemed for any primary antibody ordered and the discount code is valid for 4 months after issue.
Please remember that submission of the Abreview is sufficient for the discount code to become active.

Thank you for your patience. The originator of ab3535 has said that the antibody should not cross react with the RbAP48 protein. Please contact us again if you have any additional questions.

Thank you for your enquiry. For ab86 and ab488, the antibodies have not been tested against RbAp46 so we do not know whether or not the antibodies would react with it. I'm still waiting for information on ab3535 and will let you know when I receive.
