The linear ubiquitin (Ub) chain assembly complex (LUBAC) is an E3 ligase that specifically assembles Met1-linked (also known as linear) Ub chains that regulate nuclear factor kappa-B (NF-kappa-B) signaling. Deubiquitinases are key regulators of Ub signaling. OTULIN (also known as FAM105B) is an OTU domain deubiquitinase which specifically disassembles Met1-linked polyUb generated by LUBAC (Keusekotten K et al. 2013; Rivkin E et al. 2013). OTULIN antagonizes processes involving LUBAC, including tumor necrosis factor alpha (TNFalpha), poly(I:C), NOD2 and Wnt signaling (Fiil BK et al. 2013; Keusekotten K et al. 2013; Rivkin E et al. 2013). OTULIN interacts directly with the N-terminal PUB domain of HOIP, a component of the LUBAC complex, via a conserved PUB-interacting motif (PIM) in OTULIN (Elliott PR et al. 2014; Schaeffer V et al. 2014). Furthermore, OTULIN phosphorylation at Tyr56 within PIM was found to prevent the LUBAC:OTULIN complex formation (Elliott PR et al. 2014).
