The Transcription Elongation Regulator 1 (TCERG1) family comprises proteins that play a critical role in the regulation of transcription elongation. Members of the TCERG1 family are known to bind RNA polymerase II and inhibit the elongation of transcripts from target promoters. They are involved in the regulation of transcription elongation in a TATA box-dependent manner and are necessary for TAT-dependent activation of the HIV-1 promoter. The family is characterized by the presence of FF domains, which bind the phosphorylated C-terminus of RNA polymerase II and mediate interactions with other proteins such as HTATSF1. These domains also show a preference for peptides with a specific consensus sequence. Additionally, the WW domains within these proteins are responsible for binding to Pro-rich domains, facilitating further protein-protein interactions.	Domain
