Function

OTUL_HUMAN Deubiquitinase that specifically removes linear ('Met-1'-linked) polyubiquitin chains to substrates and acts as a regulator of angiogenesis and innate immune response. Associates with the LUBAC complex via direct interaction with RNF31 and counteracts its action by cleaving linear polyubiquitin chains to substrates. Required during angiogenesis, craniofacial and neuronal development by regulating the canonical Wnt signaling together with the LUBAC complex. Acts as a negative regulator of NF-kappa-B by counteracting activity of the LUBAC complex. Plays a key role in innate immune response: required to restrict linear polyubiquitin formation on RIPK2 in response to NOD2 stimulation, probably to limit NOD2-dependent proinflammatory signaling.^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

A complex interaction of signalling events, including the Wnt pathway, regulates sprouting of blood vessels from pre-existing vasculature during angiogenesis. Here we show that two distinct mutations in the (uro)chordate-specific gumby (also called Fam105b) gene cause an embryonic angiogenic phenotype in gumby mice. Gumby interacts with disheveled 2 (DVL2), is expressed in canonical Wnt-responsive endothelial cells and encodes an ovarian tumour domain class of deubiquitinase that specifically cleaves linear ubiquitin linkages. A crystal structure of gumby in complex with linear diubiquitin reveals how the identified mutations adversely affect substrate binding and catalytic function in line with the severity of their angiogenic phenotypes. Gumby interacts with HOIP (also called RNF31), a key component of the linear ubiquitin assembly complex, and decreases linear ubiquitination and activation of NF-kappaB-dependent transcription. This work provides support for the biological importance of linear (de)ubiquitination in angiogenesis, craniofacial and neural development and in modulating Wnt signalling.
