Accession ID	Name	Pfam Type
PF14304	Transcription termination and cleavage factor C-terminal	domain

The C-terminal section of CSTF proteins is a discreet structure is crucial for mRNA 3'-end processing. This domain interacts with Pcf11 and possibly PC4, thus linking CstF2 to transcription, transcriptional termination, and cell growth.
