Gene: TAF1 (TATA-box binding protein associated factor 1) Homo sapiens
Symbol: TAF1
Name: TATA-box binding protein associated factor 1
Description: Exhibits several functions, including RNA polymerase II general transcription initiation factor activity; lysine-acetylated histone binding activity; and transcription factor binding activity. Contributes to H3K27me3 modified histone binding activity. Involved in several processes, including cellular protein metabolic process; regulation of cellular protein metabolic process; and regulation of transcription, DNA-templated. Localizes to the MLL1 complex; nuclear chromatin; and transcription factor TFIID complex. Colocalizes with the nucleolus. Implicated in X-linked dystonia-parkinsonism and syndromic X-linked intellectual disability.
Type: protein-coding
RefSeq Status: REVIEWED
