UniProtKB description: Has an ATP-independent isopeptidase activity, cleaving at the C-terminus of the ubiquitin moiety in natural or engineered linear fusion proteins, irrespective of their size or the presence of an N-terminal extension to ubiquitin (PubMed:12778054, PubMed:17632125). Plays a role in regulation of silencing by interacting with SIR4 (PubMed:8752220). Also, in conjunction with BRE5, cleaves ubiquitin, leading to the subsequent mono-ubiquitination of SEC23 (PubMed:12778054). Required for ribophagy, a process which relocalizes ribosomal particles into the vacuole for degradation in response to starvation (PubMed:20508643).
