Gene: HTATSF1 (HIV-1 Tat specific factor 1) Homo sapiens
Symbol: HTATSF1
Name: HIV-1 Tat specific factor 1
Description: Exhibits RNA binding activity. Predicted to be involved in regulation of DNA-templated transcription, elongation; regulation of transcription by RNA polymerase II; and viral genome replication. Localizes to the nucleoplasm.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: cofactor required for Tat activation of HIV-1 transcription; dJ196E23.2; HIV TAT specific factor 1; HIV Tat-specific factor 1; TAT-SF1; TATSF1
