  • Function

    Transcriptional corepressor of NR4A2/NURR1 and acts through histone deacetylases (HDACs) to keep promoters of NR4A2/NURR1 target genes in a repressed deacetylated state (By similarity). Mediates the transcriptional repression activity of some nuclear receptors by promoting chromatin condensation, thus preventing access of the basal transcription. Isoform 1 and isoform 5 have different affinities for different nuclear receptors.
  • Tissue specificity

    Ubiquitous. High levels of expression are detected in lung, spleen and brain.
  • Sequence similarities

    Belongs to the N-CoR nuclear receptor corepressors family.
    Contains 2 SANT domains.
  • Domain

    The N-terminal region contains repression functions that are divided into three independent repression domains (RD1, RD2 and RD3). The C-terminal region contains the nuclear receptor-interacting domains that are divided in two separate interaction domains (ID1 and ID2).
    The two interaction domains (ID) contain a conserved sequence referred to as the CORNR box. This motif is required and sufficient to permit binding to unligated TR and RARS. Sequences flanking the CORNR box determine nuclear hormone receptor specificity.

I'm sorry to hear you are having a problem with ab2780. We have not had any complaints regarding this antibody, so I believe that I can give you some protocol tips to get the antibody working. I believe that the problem may be in the blocking step using 10% FBS, or a different fixation may also help. This antibody has been tested in immunohistochemistry (Frozen sections) in HeLa cells and I am assuming this is the application that you are using. I would like to suggest the following modifications to your protocol: 1) block using 10% normal goat serum 1% BSA in TBS for 2 hrs at room temp, 2) incubate in primary antibody at 1/50 in 1% NGS 1% BSA O/N at 4C, 3) incubate in secondary antibody in 1% NGS 1% BSA for 1 hr at room temp. Additionally, you could try fixing using ice cold acetone or methanol for 10 minutes instead of PFA, if the above suggestions do not work. Please let me know if this helps and do not hesitate to contact us for further advice,
