SCFFbw7 Modulates the NFκB Signaling Pathway by Targeting NFκB2 for Ubiquitination and Destruction

Abstract excerpt

The NFkB/Rel family of proteins play critical roles in a variety of cellular processes. Thus, their physiological activation is tightly controlled. Recently, the NFkB2/p100 precursor has been characterized as the fourth IkB type of suppressor for NFkB. However, the molecular mechanism(s) underlying regulated destruction of NFkB2 remains largely unknown. Here, we report that, unlike other IkBs, ubiquitination and...
