    basic FUNCTION
  • SNF2-related helicase, functioning as a coactivator of steroid receptor-mediated transcription through synergistic interactions with CARM1 and NCOA2
  • functioning as a glucocorticoid receptor coactivator
  • ATPase chromatin-remodeling machine, implicated in the transcriptional coactivation of cyclic AMP- and steroid-dependent promoters
  • SRCAP complex catalyzes ATP-dependent exchange of histone H2A/H2B dimers containing the histone variant H2A.Z into nucleosomes
  • having a coactivator function that may depend on its ability to promote incorporation of H2AFZ into chromatin
  • could catalyze deposition of H2AFZ into nucleosomes
  • recruited to promoters and is critical for the deposition of H2AFZ
  • ATPase that is the core subunit of a large multiprotein complex and was shown to incorporate the histone variant H2A.Z into nucleosomes
  • serves as a coactivator for several nuclear receptors including the androgen receptor (AR)
  • activates hormone-dependent transcription of the androgen responsive, prostate specific antigen (PSA)-Luciferase reporter gene in human prostate cells
  • plays a role in prostate cancer cell proliferation
  • SNF2-related chromatin-remodeling factor that serves as a coactivator for CREB-binding protein (CREBBP)
  • undergoes a large conformational change upon nucleosome binding
  • SRCAP chromatin remodeling complex is a novel regulator of DNA damage responses that orchestrates proper signaling and repair of DSBs in the context of chromatin
  • important physiological functions of the SRCAP complex in regulating mitochondrial maturation and promoting oxidative metabolism during heart development
  • CELLULAR PROCESS nucleotide, transcription, regulation
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    function in the notch signaling pathway
    a component
  • part of a multiprotein complex, SRCAP-containing complex supporting ATP-dependent exchange of histone dimers containing H2B and H2AFZ into mononucleosomes reconstituted with recombinant H2A, H2B, H3, and H4
  • a single heterohexameric RVB1/RVB2 ring that, together with the catalytic subunit SWR1, brackets two independently assembled multisubunit modules
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • with CBP (cAMP response element binding protein), functioning as a coactivator to regulate transcription initiated by several signaling pathways
  • functionally interacts with NCOA2 and CARM1
  • potent coactivator for CREB and CBP-mediated transcription
  • interacting with Hepatitis C virus NS3 protein (can activate the Notch-signaling pathway through binding to SRCAP)
  • PCID2 controls lymphoid lineage commitment through the regulation of SRCAP remodelling activity
  • mechanistically, SRCAP recruits the transcriptional regulator REST to the PRDM16 promoter and induces expression of this transcription factor
