"The interaction between Y91 and M86, which is lost in the mutant M86I, might, thus, also play a role in binding of OTULIN to linear ubiquitin (Fig  xref )."

"Pull-downs demonstrate that substrate-bound OTULIN associates with the linear ubiquitin chain assembly complex (LUBAC)."

"We hypothesized that C129S OTULIN was binding to M1-Ub chains in patient cells and protecting these chains from hydrolysis by WT OTULIN."

"Leu272 is located in a helix of the catalytic OTU domain that forms part of the binding pocket for M1-linked diUb, and mutation to Pro would be predicted to disrupt OTULIN Ub binding ( xref F)."

"Disease-associated mutations reside in the OTU domain and are predicted to affect binding of OTULIN to linear Ub chains."

"Since both OsOTUB1 and OTULIN hydrolyse Met1 chains, we structurally compared the binding of proximal Ub by OsOTUB1 with OTULIN to discover their similarities and differences."

"In‐depth biochemical analysis revealed how both OTULIN variants contribute to diminished OTULIN protein expression and defective hydrolysis of linear ubiquitin linkages observed in patient‐derived cells: whereas binding of OTULIN to linear ubiquitin was compromised by both variants, protein stability and catalytic activity was most affected by the OTULIN variant p."

"OTULIN binds directly to the linear ubiquitin chain assembly complex (LUBAC) composed of HOIP, HOIL‐1, and SHARPIN, which generates methionine‐1‐linked chains. xref "

"Using our OTULIN ABP we demonstrate that OTULIN is constitutively active in cells, and that substrate-bound OTULIN associates with the linear ubiquitin chain assembly complex (LUBAC)."

"In-depth biochemical analysis revealed that binding of OTULIN to linear ubiquitin is compromised by both variants; however, protein stability and catalytic activity are most affected by the OTULIN variant p."

"On the molecular level, we find binding of OTULIN to linear ubiquitin to be compromised by both variants; however, protein stability and catalytic activity is most affected by OTULIN variant p."

"It is likely, therefore, that the W167S replacement affects the orientation of the helical arm's S1 site, made up of L259, A262, and R263 toward the I44 patch of distal ubiquitin, thereby indirectly interfering with OTULIN’s binding (K M ) to linear ubiquitin (Fig  xref )."

"Collectively, this structural analysis suggests that both substitutions, M86I and W167S, may interfere with binding of OTULIN to linear ubiquitin (Fig  xref )."

"OTULIN variants compromise binding of OTULIN to linear ubiquitin and differentially affect OTULIN’s intrinsic stability and catalytic activity."

"In summary, we find binding of OTULIN to linear ubiquitin to be compromised by both variants; however, protein stability and catalytic activity is most affected by the OTULIN variant p."

"These include genetic mutations in components of the linear ubiquitin chain assembly complex (LUBAC), the linear deubiquitylase OTULIN, the ubiquitylation substrate RIPK1 and the ubiquitin-binding protein A20 xref – xref ."
