== Disease ==
[[http://www.uniprot.org/uniprot/SRCAP_HUMAN SRCAP_HUMAN]] Floating-Harbor syndrome. The disease is caused by mutations affecting the gene represented in this entry. 
== Function ==
[[http://www.uniprot.org/uniprot/SRCAP_HUMAN SRCAP_HUMAN]] Catalytic component of the SRCAP complex which mediates the ATP-dependent exchange of histone H2AZ/H2B dimers for nucleosomal H2A/H2B, leading to transcriptional regulation of selected genes by chromatin remodeling. Acts as a coactivator for CREB-mediated transcription, steroid receptor-mediated transcription, and Notch-mediated transcription.<ref>PMID:10347196</ref> <ref>PMID:11522779</ref> <ref>PMID:14500758</ref> <ref>PMID:16024792</ref> <ref>PMID:16634648</ref> <ref>PMID:17617668</ref>  [[http://www.uniprot.org/uniprot/RUVB1_HUMAN RUVB1_HUMAN]] Possesses single-stranded DNA-stimulated ATPase and ATP-dependent DNA helicase (3' to 5') activity; hexamerization is thought to be critical for ATP hydrolysis and adjacent subunits in the ring-like structure contribute to the ATPase activity.<ref>PMID:11027681</ref> <ref>PMID:14506706</ref> <ref>PMID:11080158</ref> <ref>PMID:14695187</ref> <ref>PMID:14966270</ref>   Component of the NuA4 histone acetyltransferase complex which is involved in transcriptional activation of select genes principally by acetylation of nucleosomal histones H4 and H2A. This modification may both alter nucleosome - DNA interactions and promote interaction of the modified histones with other proteins which positively regulate transcription. This complex may be required for the activation of transcriptional programs associated with oncogene and proto-oncogene mediated growth induction, tumor suppressor mediated growth arrest and replicative senescence, apoptosis, and DNA repair. The NuA4 complex ATPase and helicase activities seem to be, at least in part, contributed by the association of RUVBL1 and RUVBL2 with EP400. NuA4 may also play a direct role in DNA repair when recruited to sites of DNA damage.<ref>PMID:11027681</ref> <ref>PMID:14506706</ref> <ref>PMID:11080158</ref> <ref>PMID:14695187</ref> <ref>PMID:14966270</ref>   Proposed core component of the chromatin remodeling INO80 complex which is involved in transcriptional regulation, DNA replication and probably DNA repair.<ref>PMID:11027681</ref> <ref>PMID:14506706</ref> <ref>PMID:11080158</ref> <ref>PMID:14695187</ref> <ref>PMID:14966270</ref>   Plays an essential role in oncogenic transformation by MYC and also modulates transcriptional activation by the LEF1/TCF1-CTNNB1 complex.
