LUBAC, a novel ubiquitin ligase for linear ubiquitination, is crucial for inflammation and immune responses

LUBAC (linear ubiquitin chain assembly complex) is a ubiquitin ligase complex composed of SHARPIN, HOIL-IL and HOIP that generates linear polyubiquitin chains and regulates the NF-κB pathway, which is pivotal in inflammatory and immune responses. Recent findings on the regulation of NF-κB by LUBAC and the diseases associated with this process are the focus of this review.
