Human Gene BCOR (ENST00000342274.8)
  Description: Homo sapiens BCL6 corepressor (BCOR), transcript variant 3, mRNA. (from RefSeq NM_001123383)
RefSeq Summary (NM_001123383): The protein encoded by this gene was identified as an interacting corepressor of BCL6, a POZ/zinc finger transcription repressor that is required for germinal center formation and may influence apoptosis. This protein selectively interacts with the POZ domain of BCL6, but not with eight other POZ proteins. Specific class I and II histone deacetylases (HDACs) have been shown to interact with this protein, which suggests a possible link between the two classes of HDACs. Several transcript variants encoding different isoforms have been found for this gene. A pseudogene of this gene is found on chromosome Y.[provided by RefSeq, Jun 2010].

DESCRIPTION: RecName: Full=BCL-6 corepressor; Short=BCoR;
FUNCTION: Transcriptional corepressor. May specifically inhibit gene expression when recruited to promoter regions by sequence specific DNA-binding proteins such as BCL6 and MLLT3. This repression may be mediated at least in part by histone deacetylase activities which can associate with this corepressor. Involved in the repression of TFAP2A; impairs binding of BCL6 and KDM2B to TFAP2A promoter regions. Via repression of TFAP2A acts as a negative regulator of osteo-dentiogenic capacity in adult stem cells; the function implies inhibition of methylation on histone H3 'Lys-4' (H3K4me3) and 'Lys-36' (H3K36me2).
SUBUNIT: Isoform 1 may interact with MLLT3/AF9 (By similarity). Interacts with BCL6; the interaction is direct. Can interact with HDAC1, HDAC3 and HDAC5. Interacts with PCGF1; the interaction is direct. Interacts with KDM2B. Component of an approximative 800 kDa repressive BCOR complex at least composed of BCOR, RYBP, PCGF1, RING1, RNF2/RING2, KDM2B and SKP1.
INTERACTION: Q8NHM5:KDM2B; NbExp=2; IntAct=EBI-950027, EBI-3955564; Q9BSM1:PCGF1; NbExp=6; IntAct=EBI-950027, EBI-749901;
TISSUE SPECIFICITY: Ubiquitously expressed.
DISEASE: Defects in BCOR are the cause of microphthalmia syndromic type 2 (MCOPS2) [MIM:300166]. Microphthalmia is a clinically heterogeneous disorder of eye formation, ranging from small size of a single eye to complete bilateral absence of ocular tissues (anophthalmia). In many cases, microphthalmia/anophthalmia occurs in association with syndromes that include non-ocular abnormalities. MCOPS2 is a very rare multiple congenital anomaly syndrome characterized by eye anomalies (congenital cataract, microphthalmia, or secondary glaucoma), facial abnormalities (long narrow face, high nasal bridge, pointed nose with cartilages separated at the tip, cleft palate, or submucous cleft palate), cardiac anomalies (atrial septal defect, ventricular septal defect, or floppy mitral valve) and dental abnormalities (canine radiculomegaly, delayed dentition, oligodontia, persistent primary teeth, or variable root length).
SIMILARITY: Belongs to the BCOR family.
SIMILARITY: Contains 3 ANK repeats.

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.
