CC   -!- FUNCTION: Does not bind DNA by itself; probably associates with a p50-
CC       NF-kappa-B homolog to act as an activator. Could be involved in
CC       hematopoiesis and spleen development. May play a role in the regulation
CC       of the circadian clock.
CC   -!- SUBCELLULAR LOCATION: Nucleus.
