The MPN domain of Caenorhabditis elegans UfSP modulates both substrate recognition and deufmylation activity

Ubiquitin-fold modifier 1 (Ufm1) specific protease (UfSP) is a novel cysteine protease that activates Ufm1 from its precursor by processing the C-terminus to expose the conserved Gly necessary for substrate conjugation and de-conjugates Ufm1 from the substrate. There are two forms: UfSP1 and UfSP2,...
