{"symbol":"HTATSF1","synonyms":["TAT-SF1","TATSF1","DJ196E23.2"],"name":"HIV-1 Tat specific factor 1","description":"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]","ncbiEntrezGeneId":27336,"ncbiEntrezGeneUrl":"http://www.ncbi.nlm.nih.gov/gene/27336","proteins":[{"symbol":"HTSF1_HUMAN","href":"/api/1.0/protein/HTSF1_HUMAN"}],"hgncRootFamilies":[{"name":"RNA binding motif containing (RBM)","href":"/api/1.0/gene_family/RNA+binding+motif+containing+%28RBM%29"}]}
