Target

  • Relevance
    Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post- modifications of histones, also called histone code, and nucleosome remodeling. P68431 and Q71DI3 are expressed during S phase, then expression strongly decreases as cell division slows down during the process of differentiation. Q16695 is expressed in tesicular cells. Q6NXT2 is specifically expressed in the seminiferous tubules of testis and this Hominid-specific H3.5/H3F3C preferentially colocalizes with euchromatin, and it is associated with actively transcribed genes. P84243 is a variant histone H3 which replaces conventional H3 in a wide range of nucleosomes in active genes. Constitutes the predominant form of histone H3 in non-dividing cells and is incorporated into chromatin independently of DNA synthesis. Deposited at sites of nucleosomal displacement throughout transcribed genes, suggesting that it represents an epigenetic imprint of transcriptionally active chromatin. Post-translational modification. Citrullination at Arg-9 (H3R8ci) and/or Arg-18 (H3R17ci) by PADI4 impairs methylation and represses transcription.

Images

  • ab174992 staining Histone H3 (citrulline R2) in HeLa cells. The cells were fixed with 100% methanol (5min) and then blocked in 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated with ab174992 at 5µg/ml and ab7291 (anti beta Tubulin) at 1µg/ml overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat anti-rabbit AlexaFluor®488 secondary antibody (ab150081) at 2 μg/ml (shown in green) and a goat anti-mouse AlexaFluor®594 (ab150120) at 2 μg/ml (shown in pseudo color red). Nuclear DNA was labelled in blue with DAPI.

    Negative controls: 1– Rabbit primary antibody and anti-mouse secondary antibody; 2 – Mouse primary antibody and anti-rabbit secondary antibody. Controls 1 and 2 indicate that there is no unspecific reaction between primary and secondary antibodies used.

    Predicted band size: 15 kDa
    Observed band size: 18 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 77 kDa (possible non-specific binding)


    Exposure time: 2 minutes


    This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab174992 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406
