== Function ==
[https://www.uniprot.org/uniprot/SST2_SCHPO SST2_SCHPO] Zinc metalloprotease that specifically cleaves 'Lys-63'-linked polyubiquitin chains. Does not cleave 'Lys-48'-linked polyubiquitin chains (By similarity). Plays a role in the multivesicular body (MVB) sorting pathway. Required for ubiquitin-dependent sorting of proteins into the endosome and subsequent trafficking to the vacuole. May regulate MVB sorting through deubiquitination of ubiquitinated ESCRT proteins.<ref>PMID:17660439</ref>
