Fig. 1From: Role of the ubiquitin ligase KPC1 in NF-κB activation and tumor suppressionThe multi-step activation pathway of the NF-κB transcription factor. For details, see the main text. Yellow circles denote Ub48-linked chains. Orange circles denote K64-based chains. Blue circles denote linear Ub chains. The yellow arrow denotes ubiquitination. The green arrow denotes de-ubiquitination. The red arrow denotes phosphorylationBack to article page
