pfam11526: Pfc11_Clp1_ID (This model is not part of the current CDD release)
Pcf11, Clp1-interaction domain
Pcf11 is a subunit and an essential component of the cleavage and polyadenylation factor CFIA from yeast and the orthologue from human CFII which is involved in pre-mRNA 3' end processing and in transcription termination. Pcf11-mediated termination is essential for vertebrate development. Pcf11 binds to Clp1, another subunit of CFIA/CFII, whose interaction is responsible for maintaining a tight coupling between the Clp1 nucleotide binding subunit and the other components of the polyadenylation machinery. This entry represents the Clp1-interaction region (Clp1 ID) of Pcf11 from yeast and vertebrates.
