Centrosome-associated zinc finger protein CP190; Component of the gypsy chromatin insulator complex which is required for the function of the gypsy chromatin insulator and other endogenous chromatin insulators. Chromatin insulators are regulatory elements which establish independent domains of transcriptional activity within eukaryotic genomes. Insulators have two defining properties; they can block the communication between an enhancer and a promoter when placed between them and can also buffer transgenes from position effect variegation (PEV). Insulators are proposed to structure the [...]

Nucleosome-remodeling factor subunit NURF301; Histone-binding component of NURF (nucleosome remodeling factor), a complex which catalyzes ATP-dependent nucleosome sliding and facilitates transcription of chromatin. Specifically recognizes H3 tails trimethylated on 'Lys-4' (H3K4me3), which mark transcription start sites of virtually all active genes. Required for homeotic gene expression, proper larval blood cell development, normal male X chromosome morphology, ecdysteroid signaling and metamorphosis. Belongs to the BPTF family.

DNA replication-related element factor (Dref) encodes a BED finger-type transcription factor that binds to the DRE sequence (TATCGATA). The Dref product is involved in tumor suppressor, TOR, JNK and EGFR signalling pathways. It also plays a role in chromatin organization including insulator function, chromatin remodeling, and telomere maintenance.

TATA box binding protein-related factor 2 (Trf2) encodes a core promoter recognition factor that mediates gene transcription. It contributes to spiracle morphogenesis, pupal development and salivary gland cell death.

Chromosomal serine/threonine-protein kinase JIL-1; Phosphorylates 'Ser-10' of histone H3. May regulate gene expression by establishing or maintaining the structure of more open chromatin regions. Also required for normal polytene chromosome structure, for oogenesis and for viability throughout development. Regulates the structure of polytene chromosomes in salivary glands. May phosphorylate 'Ser-1' of histone H2A.

Inorganic pyrophosphatase; Component of NURF (nucleosome remodeling factor), a complex which catalyzes ATP-dependent nucleosome sliding and facilitates transcription of chromatin. NURF is required for homeotic gene expression, proper larval blood cell development, normal male X chromosome morphology, ecdysteroid signaling and metamorphosis. Nurf-38 may have adapted to deliver pyrophosphatase to chromatin to assist in replication or transcription by efficient removal of the inhibitory metabolite; Belongs to the PPase family.

Relative of woc (row) encodes a zinc-finger protein involved in transcription regulation that is required for the factor encoded by HP1c to bind chromatin.

Probable histone-binding protein Caf1; 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; the nucleosome remodeling and deacetylase complex (the NuRD complex), which promotes transcriptional repression by histone deacetylati [...]

BRWD3 (BRWD3) encodes a member of the Bromodomain and WD repeat_containing protein (BRWD) family. It regulates ecdysone and JAK-STAT signaling pathways and contributes to eye development, cell death and phagocytosis.
