The Rel/ NF-kappa B family of transcription factors is composed of two distinct subgroups, proteins that undergo proteolytic processing and contain SWI6/ankyrin repeats in their carboxyl termini ( p105 , p98 ), and those without such repeats that do not require processing ( p65 , c-Rel , RelB , and Dorsal ).
