The Linear ubiquitin chain assembly complex acts as a liver tumor suppressor and inhibits hepatocyte apoptosis and hepatitis

Yutaka Shimizu, Nieves Peltzer, Alexandra Sevko, Elodie Lafont, Aida Sarr, Helena Draberova, Henning Walczak – 24 January 2017 – Linear ubiquitination is a key posttranslational modification that regulates immune signaling and cell death pathways, notably tumor necrosis factor receptor 1 (TNFR1) signaling. The only known enzyme complex capable of forming linear ubiquitin chains under native conditions to date is the linear ubiquitin chain assembly complex, of which the catalytic core component is heme‐oxidized iron regulatory protein 2 ubiquitin ligase‐1–interacting protein (HOIP).
