BRD4 bromodomain containing 4 [Homo sapiens (human)] - Gene

Summary

Official Symbol: BRD4provided by HGNC
Official Full Name: bromodomain containing 4provided by HGNC
Primary source: HGNC:HGNC:13575
See related: Ensembl:ENSG00000141867 MIM:608749; AllianceGenome:HGNC:13575
Gene type: protein coding
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; CDLS6; HUNK1; HUNKI; FSHRG4
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]

	tat	JQ1, a small molecule inhibitor of Brd4, directly dissociates Brd4 from HIV-1 promoter and promotes subsequently HIV-1 Tat binding to HIV-1 promoter, resulting in increased phosphorylation of RNA polymerase II and viral transcription	PubMed

RefSeqs maintained independently of Annotated Genomes

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.
