Lee et al. identify MST1 as a component of TNF-RSC that phosphorylates HOIP at serine 1,066 and thereby inhibits the linear ubiquitin chain-forming activity of LUBAC in a TRAF2-dependent manner. MST1, by inhibiting an E3 ligase activity of HOIP, negatively regulates the NF-κB-dependent inflammatory gene expression induced by TNFα.
