  • General notes

    Complex that assembles histone octamers onto replicating DNA in vitro. Caf-1 performs the first step of the nucleosome assembly process, bringing newly synthesized histones h3 and h4 to replicating DNA; histones H2a/H2b can bind to this chromatin precursor subsequent to DNA replication to complete the histone octamer. P150 and p60 form complexes with newly synthesized histones h3 and acetylated H4 in cell extracts (by similarity). P55 associates with acetyltransferases and deacetylases in cell extracts and is also a component of the nucleosome remodeling factor complex (NURF), a protein complex consisting of four polypeptides that facilitates the perturbation of chromatin structure in vitro in an ATP-dependent manner. This subunit may assist targeting of protein complexes to chromatin.



Our Abpromise guarantee covers the use of ab1766 in the following tested applications.

  • Relevance
    p55/DCAF1 is a core histone-binding subunit that may target chromatin assembly factors, chromatin remodeling factors 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 chromatin assembly factor 1 (CAF-1) complex, which is required for chromatin assembly following DNA replication and DNA repair.

    • Chromatin was obtained from Kc167 cells fixed with formaldehyde for 10 min. The ChIP was performed with 30-40 µg of chromatin, ab1766 at 1/450 dilution (incubated with samples for 16h at 4°C) and 20µl of Protein G Agarose beads per ChIP. The immunoprecipitated DNA was quantified by real time PCR (SYBR) . Gene A's enhancer region locus (positive control) shows enrichment when compared with it's coding sequence locus (negative control).
