Linear Penta-Ubiquitin - 100 µg

**This chain is not recognized by LUB-9, the linear chain-specific monoclonal antibody, nor is it cleaved by Otulin (aka Gumby), the linear chain-specific DUB.**-\n-\nA wide range of cellular processes are modulated through the generation and attachment of polyubiquitin (polyUb) chains to target proteins.  Increasing evidence suggests that polyUb chains joined through linear peptide bonds between the C-terminus of a ubiquitin and the N-terminus of another play important functional roles. The enzyme machinery responsible for the generation of linear polyUb chains has been termed LUBAC, consisting of HOIL-1L and HOIP. Chains of these type have an open conformation, similar to polyUb K63, but with very distinct functional properties. Linear polyUb chains are cleaved by the deubiquitylases CYLD, USP5 (IsoT), USP2 and have been shown to bind to many UBDs including NEMO and Trabin-n (3xnzf). Recombinant pentaubiquitin expressed as a linear chain.
