Description: Homo sapiens polycomb group ring finger 1 (PCGF1), mRNA. RefSeq Summary (NM_032673): PCGF1 is a mammalian homolog of the Drosophila polycomb group genes, which act as transcriptional repressors to regulate anterior-posterior patterning in early embryonic development (Nunes et al., 2001 [PubMed 11287196]). See also PCGF2 (MIM 600346).[supplied by OMIM, Aug 2008]. Transcript (Including UTRs) Position: hg19 chr2:74,732,170-74,734,821 Size: 2,652 Total Exon Count: 9 Strand: - Coding Region Position: hg19 chr2:74,732,270-74,734,795 Size: 2,526 Coding Exon Count: 9
ID:PCGF1_HUMAN DESCRIPTION: RecName: Full=Polycomb group RING finger protein 1; AltName: Full=Nervous system Polycomb-1; Short=NSPc1; AltName: Full=RING finger protein 68; FUNCTION: Component of the Polycomb group (PcG) multiprotein BCOR complex, a complex required to maintain the transcriptionally repressive state of some genes, such as BCL6 and the cyclin- dependent kinase inhibitor, CDKN1A. Transcriptional repressor that may be targeted to the DNA by BCL6; this transcription repressor activity may be related to PKC signaling pathway. Represses CDKN1A expression by binding to its promoter, and this repression is dependent on the retinoic acid response element (RARE element). Promotes cell cycle progression and enhances cell proliferation as well. May have a positive role in tumor cell growth by down- regulating CDKN1A. Component of a Polycomb group (PcG) multiprotein PRC1-like complex, a complex class required to maintain the transcriptionally repressive state of many genes, including Hox genes, throughout development. PcG PRC1 complex acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A 'Lys-119', rendering chromatin heritably changed in its expressibility. SUBUNIT: Component of repressive BCOR complex containing Polycomb group subcomplex at least composed of RYBP, RING1 and RNF2/RING2. Specifically interacts with BCOR, RING1 and RNF2/RING2. Component of a PRC1-like complex. Interacts with CBX6, CBX7 and CBX8. INTERACTION: Q6W2J9:BCOR; NbExp=6; IntAct=EBI-749901, EBI-950027; Q9HC52:CBX8; NbExp=2; IntAct=EBI-749901, EBI-712912; Q06587:RING1; NbExp=5; IntAct=EBI-749901, EBI-752313; Q99496:RNF2; NbExp=4; IntAct=EBI-749901, EBI-722416; SUBCELLULAR LOCATION: Nucleus. TISSUE SPECIFICITY: Ubiquitous. SIMILARITY: Contains 1 RING-type zinc finger. SEQUENCE CAUTION: Sequence=AAH04952.1; Type=Erroneous initiation; Sequence=AAP97183.1; Type=Erroneous initiation;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
