  • N-terminal region interacts with the acetyltransferases
  • a bromodomain six zinc finger motifs with a unique assembly of zinc fingers, termed a PZP domain
  • a leucine zipper domain
  • a motif called PZPM (PHD/Zn-knuckle/PHD Motif) ,
  • two PHD fingers, for potential interactions with histones
  • an enhancer of polycomb (EPc) homology domain in the middle part binds to ING5 and MEAF6
  • a PWWP domain tha is a H3K36me3 binding module , and is absolutely essential for BRPF1 function
  • four nucleosome-binding domains
  • an unstructured 18-AA region at the C-terminal end of the catalytic domain is required for BRPF1 interaction (Ullah 2008)

    basic FUNCTION
  • functioning as a transcriptional co-activator
  • may be a part of the general transcriptional machinery
  • recruits KAT6A to distinct sites of active chromatin and remains at chromosomes during mitosis, mediated by direct histone binding of its bromodomain, which has a preference for acetylated histones
  • acts by multiple mechanisms to mediate KAT6A-dependent histone acetylation and to mark HOX genes for maintained expression throughout vertebrate development
  • enhances the transcriptional potential of KAT6A and a leukemic KAT6A-NCOA2 fusion protein (BRPF proteins play a key role in assembling and activating KAT6A/KAT6B acetyltransferase complexes)
  • play a key role in assembling and activating KAT6A/KAT6B acetyltransferase complexes
  • contributes to transcriptional memory throughout mitosis
  • scaffold component in a couple of histone acetyltransferase (HATs) complexes
  • important role in regulating forebrain development, suggesting that it acts as both an activator and a silencer of gene expression
  • plays a scaffolding role in transcription
  • essential role of the multivalent chromatin regulator BRPF1 in definitive hematopoiesis
  • is a multivalent chromatin regulator possessing three histone-binding domains, one non-specific DNA-binding module, and several motifs for interacting with and activating three lysine acetyltransferases
  • CELLULAR PROCESS nucleotide, transcription, regulation
    a component
  • MYST3 and the related factor MYST4 form tetrameric complexes with ING5 (inhibitor of growth 5), MEAF6 (Esa1-associated factor 6 ortholog), and the bromodomain-PHD finger protein BRPF1, -2, or -3 (Ullah 2009)
  • subunit of the KAT6A/KAT6A H3 HAT complex
  • core subunit of the MOZ histone acetyltransferase (HAT) complex, critical for normal developmental programs and implicated in acute leukemias
    small molecule metal binding,
  • Zn2+
  • protein
  • functions in association with the histone acetyltransferase KAT6A, an interaction mediated by the N-terminal domain of BRPF1, and promotes histone acetylation
  • BRPF1, BRD1, BRPF3 bridge the association of KAT6A and KAT6B with ING5 and MEAF6
  • ZFAT-regulated BRPF1 expression was likely important for T-cell survival
