CC   -!- FUNCTION: Hydrolase that can remove conjugated ubiquitin from proteins
CC       and may therefore play an important regulatory role at the level of
CC       protein turnover by preventing degradation (By similarity). May be
CC       involved in TIV genomic DNA packaging in a manner related to the Gag
CC       polyproteins of the mammalian viruses. {ECO:0000250,
CC       ECO:0000269|PubMed:1701750}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Thiol-dependent hydrolysis of ester, thioester, amide, peptide
CC         and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-
CC         residue protein attached to proteins as an intracellular targeting
CC         signal).; EC=3.4.19.12; Evidence={ECO:0000250|UniProtKB:Q5VVQ6};
