Transcription factor NF-ĸB is a key regulator of immunity in mammals, but its function in protists like Capsaspora and choanoflagellates is not known. Here, Leah Williams et al. characterize and compare the structure, activity, and regulation of NF-ĸB from Capsaspora and one choanoflagellate, providing further insight into the origins of NF-ĸB.
