RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: CAP; MCAP; HUNK1; HUNKI
Summary: The protein encoded by this gene is homologous to the murine protein MCAP, which associates with chromosomes during mitosis, and to the human RING3 protein, a serine/threonine kinase. Each of these proteins contains two bromodomains, a conserved sequence motif which may be involved in chromatin targeting. This gene has been implicated as the chromosome 19 target of translocation t(15;19)(q13;p13.1), which defines an upper respiratory tract carcinoma in young people. Two alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2008]
Expression: Ubiquitous expression in placenta (RPKM 10.8), testis (RPKM 9.2) and 25 other tissues See more

Study shows that BRD4 is significantly highly expressed in gastric cancer patients and cell lines and positively regulates the expression of c-MYC through transcription regulation and epigenetic levels. Functionally, these result demonstrate that the knockdown of BRD4 represses the proliferation and induces the apoptosis of gastric cancer cells through repression of c-MYC.

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
