Gene Group (FlyBase)
BRAHMA ASSOCIATED PROTEINS COMPLEX -
The Brahma associated proteins (BAP) complex is an ATP-dependent chromatin remodeling complex. (Adapted from FBrf0192510.)
POLYBROMO-CONTAINING BRAHMA ASSOCIATED PROTEINS COMPLEX -
Brahma (BRM) complexes are ATP-dependent chromatin remodeling complexes. The Polybromo-containing Brahma associated proteins (PBAP) complex is distinguished by the presence of polybromo and Bap170 subunits. (Adapted from FBrf0192510.)
SNF2-LIKE CHROMATIN REMODELERS -
Snf2-like chromatin remodelers are a family of helicase-like proteins that direct energy derived from ATP hydrolysis into the mechanical remodelling of chromatin structure. They are so-called due to the presence of a domain homologous to the helicase-like ATPase domain of the S. cerevisiae Snf2 protein. This domain, the Snf2 domain, consists of two tandem RecA-like folds and contains seven conserved helicase-related sequence motifs that classify it as part of the helicase superfamily 2 (SF2). However, Snf2 proteins are not bona fide helicases, lacking the ability to separate nucleic acid strands. Instead, Snf2 proteins are DNA translocases that apply an ATP-dependent torsional strain to DNA, which provides the necessary force to remodel nucleosomes or in some cases other DNA-protein complexes. (Adapted from PMID:21862382.)
NON-CANONICAL BRAHMA ASSOCIATED PROTEINS COMPLEX -
Brahma (BRM) complexes are ATP-dependent chromatin remodeling complexes. The non-canonical BAP (ncBAP) complex is distinguished by the presence of a Bicra subunit. (Adapted from FBrf0247407.)
Protein Function (UniProtKB)
Transcriptional regulator (PubMed:1346755). Acts as a coactivator, assisting one or more dedicated transcriptional activators of ANTC and BXC homeotic gene clusters (PubMed:1346755). Can counteract the repressive effect of Polycomb protein (PubMed:1346755). ATPase subunit of the Brahma complex, a multiprotein complex which is the equivalent of the yeast SWI/SNF complex and acts by remodeling the chromatin by catalyzing an ATP-dependent alteration in the structure of nucleosomal DNA (PubMed:1346755). This complex can both serve as a transcriptional coactivator or corepressor, depending on the context (PubMed:10809665). In type II neuroblast lineage, as part of the Brm remodeling complex, suppresses the formation of ectopic neuroblasts probably through interaction with erm and HDAC3 (PubMed:24618901).
(UniProt, P25439)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
brm: brahma (J.A. Kennison)
Dominant suppressor of Pc and Pcl alleles. Recessive embryonic lethal with strong maternal contribution. Maternal effect lethality is non-rescuable even by two wildtype zygotic alleles. There is a single 5.5 kb mRNA present throughout development with the greatest amounts in the unfertilized egg and early embryo. brm1 isolated as a dominant suppressor of the antennal to leg transformation associated with a Pc2 AntpNs double heterozygote.
Summary (Interactive Fly)

transcription factor - SWI2/SNF2 homolog - overcomes the repressive effect of chromatin to activate gene transcription - fine-tunes circadian transcription - regulates the Hippo pathway activity through forming complex with Yorkie-Scalloped and regulating the transcription of Crumbs

      DNA-protein interactions: genome-wide binding profile assayed for brm protein in S2 cells; GEO accession number GSE32404.

      The 'l(3)72Aa' (brm) complementation group comprises 19 EMS-induced mutant alleles.

      DNA-protein interactions: genome-wide binding profile assayed for brm protein in Kc167 cells; see Chromatin_types_NKI collection report. Individual protein-binding experiments listed under "Samples" at GEO_GSE22069 (http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE22069).

      dsRNA has been made from templates generated with primers directed against this gene. RNAi of brm disrupts the dendritic routing patterns of the ddaD and ddaE neurons, resulting in aberrantly oriented primary dendrites. RNAi also causes defects in muscle, alterations in the number of MD neurons, defects in dendrite morphogenesis but no obvious defects in da dendrite development.

      S2 cells treated with dsRNA generated against this gene show reduced phagocytosis of Candida albicans compared to untreated cells.

      Loss of brm function results in loss of veins in the wing.

      D.melanogaster contains two distinct brahma (BRM) complexes: the BAP complex, defined by the presence of osa protein and the absence of both polybromo and Bap170 proteins, and the PBAP complex, which contains the polybromo and Bap170 proteins but lacks the osa protein.

      The chromatin remodelling activity of the brm complex may play a general role in facilitating transcription by RNA polymerase II.

      Pc, Scm, Psc, ph-p and ph-d contribute to the PRC1 (Polycomb repressive complex 1). PRC1 directly antagonizes ATP-dependent remodeling of nucleosomal arrays in a purified system and may directly modulate (and be modified by) SWI/SNF (brm/mor) activity.

      brm interacts with osa to regulate the expression of the Antp P2 promoter.

      Used in an investigation to address the relationship between retrotransposons and retroviruses and the coadaptation of these retroelements to their host genomes. Results indicate retrotransposons are heterogeneous in contrast to retroviruses, suggesting different modes of evolution by slippage-like mechanisms.

      The Snr1 and brm proteins are present in a large complex and co-precipitate from extracts, these results suggest that the Drosophila counterpart of the yeast SWI/SNF complex plays an important role in counteracting the repressive effects of chromatin on homeotic gene transcription during development.

      Phenotypic studies and genetic interactions suggest that Snr1 and brm act together, and with trx, to regulate homeotic gene transcription. Snr1 and brm proteins are present in a large complex, this complex may play an important role in maintaining homeotic gene transcription during development by counteracting the repressive effect of chromatin.

      brm is a positive transcriptional regulator of hh in imaginal development.

      Regions of the Scr regulatory region may be important for regulation of Scr by Polycomb- and trithorax-group genes.

      A method based on in-vivo formaldehyde crosslinking and chromatin immunoprecipitation has allowed the determination of the in vivo distribution of Pc, brm and Abd-B products at their target sites.

      Severe abnormalities caused by loss of brm expression demonstrates that homeotic genes are not the only target for brm activation. The complex pattern of interallelic complementation suggests that brm may act as a multimer.

      Maternal and zygotic functions of brm are required during embryogenesis.

      Mutations cannot rescue the lethality of the Df(1)ph-2-Psc1 interaction, demonstrating that trx group mutations cannot suppress Pc group phenotypes.

      The ATPase domains of brm and Scer\snf2, but not Iswi, are functionally interchangeable.

      Heterozygous brm mutations suppress the dominant phenotypes of Pc and Pcl mutations.

      brm functions as an upstream activator of Scr expression and activates the Antp promoter directly.

      brm is one of the 18 loci identified in a screen for dominant modifiers of Pc and/or Antp phenotypes. Alleles of Pc, Pcl, Scm, Dll, brm, kto, Scr and trx show clear dominant enhancement or suppression of AntpScx, whereas alleles of vtd, Vha55, Su(Pc)37D, urd, mor, skd and osa do not.

      Identified as dominant suppressor of Pc and Pcl alleles. Mutants cause recessive embryonic lethal with strong maternal contribution. Maternal effect lethality is non-rescuable even by two wild-type zygotic alleles.

      Additional comments

      Source for merge of brm CG18438 was sequence comparison ( date:001104 ).

      A chimeric Scer\snf2-brm protein (in which the DNA-dependent ATPase domain of Scer\snf2 has been replaced with the corresponding region of brm) partially rescues the growth defects of S.cerevisiae Scer\snf2 mutant cells.

      Fifteen alleles induced by EMS, three alleles induced by γ irradiation and four alleles induced by hybrid dysgenesis.
