This domain is found in human Transcription factor IIIB 50 kDa subunit (BRF2) and similar sequences mainly found in eukaryotes. BRF2 is a general activator of RNA polymerase III transcription. This protein consists of an N-terminal zinc ribbon (Pfam:PF08271), a core domain consisting of two cyclin fold imperfect repeats and a C-terminal domain. This entry represents the second or C-terminal cyclin repeat [1-3].	Domain
