Western blot analysis of extracts from various cell lines using AEBP2 (D7C6X) Rabbit mAb.
Western blot analysis of extracts from HeLa cells, transfected with 100 nM SignalSilence® Control siRNA (Unconjugated) #6568 (-), SignalSilence® AEBP2 siRNA I #14711 (+), or SignalSilence® AEBP2 siRNA II #14713 (+), using AEBP2 (D7C6X) Rabbit mAb (upper) or α-Actinin (D6F6) XP® Rabbit mAb #6487 (lower). The AEBP2 (D7C6X) Rabbit mAb confirms silencing of AEBP2 expression, while the α-Actinin (D6F6) XP® Rabbit mAb is used as a loading control.
Immunoprecipitation of AEBP2 from NCCIT cell extracts using Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 (lane 2) or AEBP2 (D7C6X) Rabbit mAb (lane 3). Lane 1 is 10% input. Western blot analysis was performed using AEBP2 (D7C6X) Rabbit mAb.
Chromatin immunoprecipitations were performed with cross-linked chromatin from NCCIT cells and either JARID2 (D6M9X) Rabbit mAb #13594, CBX8 (D2O8C) Rabbit mAb #14696, or AEBP2 (D7C6X) Rabbit mAb, using SimpleChIP® Plus Enzymatic Chromatin IP Kit (Magnetic Beads) #9005. DNA Libraries were prepared using SimpleChIP® ChIP-seq DNA Library Prep Kit for Illumina® #56795. All of JARID2, CBX8, and AEBP2 are known to associate with PRC complexes. The figure shows binding of JARID2, CBX8, and AEBP2 across HOXA gene region, known target genes of JARID2, CBX8, and AEBP2 (see additional figure containing ChIP-qPCR data). For additional ChIP-seq tracks, please download the product data sheet.
Chromatin immunoprecipitations were performed with cross-linked chromatin from NCCIT cells and either AEBP2 (D7C6X) Rabbit mAb or Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human HoxA1 Intron 1 Primers #7707, SimpleChIP® Human HoxA2 Promoter Primers #5517, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
Polycomb group (PcG) proteins contribute to the maintenance of cell identity, stem cell self-renewal, cell cycle regulation, and oncogenesis by maintaining the silenced state of genes that promote cell lineage specification, cell death, and cell-cycle arrest (1-4). PcG proteins exist in two complexes that cooperate to maintain long-term gene silencing through epigenetic chromatin modifications. The PRC2 (EZH2-EED) complex is recruited to genes by DNA-binding transcription factors and methylates histone H3 on Lys27. Methylation of Lys27 facilitates the recruitment of the PRC1 complex, which ubiquitinylates histone H2A on Lys119 (5). Suppressor of Zeste 12 (SUZ12) is an obligate component of the PRC2 complex, which together with EZH2 and EED is absolutely required for histone methyltransferase activity of the protein complex (6).
The zinc finger AE binding protein 2 (AEBP2) is another integral component of the PRC2 complex. Addition of AEBP2 to the PRC2 core complex (EZH2-EED-SUZ12) enhances histone H3 Lys27 methyltransferase activity on nucleosomal substrates in vitro, which may be mediated in part by three AEBP2 DNA-binding zinc finger domains (5,7). AEBP2-mediated enhancement of enzymatic activity is greater on nucleosomal substrates that contain mono-ubiquitinated histone H2A Lys119, which suggests that AEBP2 may target PRC2 complexes in vivo through binding to DNA and mono-ubiquitinated histone H2A Lys119 (8).
