Summaries for BCOR Gene

Entrez Gene Summary for BCOR Gene

  • 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]

CIViC summary for BCOR Gene

GeneCards Summary for BCOR Gene

BCOR (BCL6 Corepressor) is a Protein Coding gene. Diseases associated with BCOR include Microphthalmia, Syndromic 2 and Microphthalmia, Syndromic 1. Among its related pathways are Signaling events mediated by HDAC Class II and Ectoderm Differentiation. Gene Ontology (GO) annotations related to this gene include transcription factor binding and transcription regulatory region DNA binding. An important paralog of this gene is BCORL1.

UniProtKB/Swiss-Prot for BCOR Gene

  • 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).

  • Microphthalmia, syndromic, 2 (MCOPS2) [MIM:300166]: 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). Microphthalmia is a 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. {ECO:0000269 PubMed:15004558}.
