Human Gene BRD2 (uc011hfq.2) Description and Page Index
  Description: Homo sapiens bromodomain containing 2 (BRD2), transcript variant 1, mRNA.
RefSeq Summary (NM_005104): This gene encodes a transcriptional regulator that belongs to the BET (bromodomains and extra terminal domain) family of proteins. This protein associates with transcription complexes and with acetylated chromatin during mitosis, and it selectively binds to the acetylated lysine-12 residue of histone H4 via its two bromodomains. The gene maps to the major histocompatability complex (MHC) class II region on chromosome 6p21.3, but sequence comparison suggests that the protein is not involved in the immune response. This gene has been implicated in juvenile myoclonic epilepsy, a common form of epilepsy that becomes apparent in adolescence. Multiple alternatively spliced variants have been described for this gene. [provided by RefSeq, Dec 2010].

-  Comments and Description Text from UniProtKB
DESCRIPTION: RecName: Full=Bromodomain-containing protein 2; AltName: Full=O27.1.1; AltName: Full=Really interesting new gene 3 protein;
FUNCTION: May play a role in spermatogenesis or folliculogenesis (By similarity). Binds hyperacetylated chromatin and plays a role in the regulation of transcription, probably by chromatin remodeling. Regulates transcription of the CCND1 gene. Plays a role in nucleosome assembly.
SUBUNIT: Homodimer. Interacts with E2F1 and with histone H4 acetylated at 'Lys-13'.
INTERACTION: P62805:HIST2H4B; NbExp=5; IntAct=EBI-2874802, EBI-302023;
SUBCELLULAR LOCATION: Nucleus (Probable). Note=Detected on chromatin and nucleosomes.
DOMAIN: One bromodomain is sufficient for a partial interaction with histone H4 acetylated at 'Lys-13'.
SIMILARITY: Contains 2 bromo domains.
SIMILARITY: Contains 1 NET domain.
SEQUENCE CAUTION: Sequence=AAA68890.1; Type=Erroneous initiation;

ModBase Predicted Comparative 3D Structure on P25440
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.
