Here, we report on the production of milligrams of highly pure Josephin mono-ubiquitinated on lysine 117 through big scale in vitro enzymatic ubiquitination. Josephin is definitely the catalytic domain of ataxin-3, a protein responsible for spinocerebellar ataxia type 3. Ataxin-3 could be the first deubiquitinating enzyme (DUB) reported to become activated by mono-ubiquitination. We demonstrate that the samples produced with the described technique are correctly folded and appropriate for structural research. The protocol enables facile selective labelling of your elements. Our final results present an essential proof-of-concept that might pave the method to new approaches for the in vitro study of ubiquitinated proteins. C 2013 The Authors.
