HTATSF1, Official Symbol HTATSF1provided by HGNC Official Full Name HIV-1 Tat specific factor 1provided by HGNC Primary source HGNC:HGNC:5276 See related Ensembl:ENSG00000102241 MIM:300346; AllianceGenome:HGNC:5276 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 TATSF1; TAT-SF1; dJ196E23.2 Summary The protein encoded by this gene functions as a cofactor for the stimulation of transcriptional elongation by HIV-1 Tat, which binds to the HIV-1 promoter through Tat-TAR interaction. This protein may also serve as a dual-function factor to couple transcription and splicing and to facilitate their reciprocal activation. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Sep 2009] Expression Ubiquitous expression in adrenal (RPKM 48.7), brain (RPKM 28.0) and 25 other tissues See more Orthologs mouse all
