There is only one protein coding transcript and one polypeptide associated with this gene
Interacts with Su(var)3-9. Component of a form of the Esc/E(z) complex present specifically during early embryogenesis which is composed of Caf1-55, esc, E(z), Su(z)12, Pcl and Rpd3. The Esc/E(z) complex may also associate with Pcl and Rpd3 during early embryogenesis. This complex is distinct from the PRC1 complex, which contains many other PcG proteins like Pc, Ph, Psc, Su(z)2. The 2 complexes however cooperate and interact together during the first 3 hours of development to establish PcG silencing. Interacts with the histone methyltransferase Su(var)3-9. Component of a complex that contains at least Rpd3, CoRest and Su(var)3-3/Hdm. Component of the DREAM complex at least composed of Myb, Caf1-55, mip40, mip120, mip130, E2f2, Dp, Rbf, Rbf2, lin-52, Rpd3 and l(3)mbt. Interacts with neuronal repressor Ttk88.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
Source for identity of: HDAC1 Rpd3
Renamed from 'Rpd3' to 'HDAC1' (a popular synonym) to be consistent with the naming convention of the other D. melanogaster HDAC genes (i.e. named after the mammalian orthologs).
DNA-protein interactions: genome-wide binding profile assayed for Rpd3 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).
Gene expression is increased in response to the presence of two copies of Scer\GAL4hs.PB.
S2 cell populations treated with dsRNA made from templates generated with primers directed against Rpd3 show inhibition of cell growth due to a G2 arrest.
dsRNA has been made from templates generated with primers directed against this gene. RNAi of Rpd3 results in increased arborization of ddaD and ddaE neurons, defects in muscle, defects in dendrite morphogenesis and reproducible defects in da dendrite development.
Rpd3 may be a component of the silencing complex for chromatin modification on specific regulatory regions of the homeotic genes.
Specific missense mutations in Rpd3 suppress the silencing of genes subject to PEV, perhaps by acting as antimorphs that poisen the deacetylase complex.
Mutational analysis indicates that the Rpd3 histone deacetylase acts as a global transcriptional regulator.
The Rpd3 histone deacetylase is required for segmentation of the Drosophila embryo.
Loss of Rpd3 results in increased genomic silencing, which decreases the distance from heterochromatin.
