CC -!- FUNCTION: Ubiquitin thioesterase, which specifically hydrolyzes 'Lys-
CC 29'-linked and 'Lys-33'-linked diubiquitin (By similarity). Also
CC cleaves 'Lys-63'-linked chains, but with 40-fold less efficiency
CC compared to 'Lys-29'-linked ones (By similarity). Positive regulator of
CC the Wnt signaling pathway that deubiquitinates apc protein, a negative
CC regulator of Wnt-mediated transcription (By similarity). Acts as a
CC regulator of autophagy by mediating deubiquitination of pik3c3/vps34,
CC thereby promoting autophagosome maturation (By similarity). Plays a
CC role in the regulation of cell morphology and cytoskeletal organization
CC (By similarity). Required in the stress fiber dynamics and cell
CC migration (By similarity). {ECO:0000250|UniProtKB:Q9UGI0}.
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:Q9UGI0};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9UGI0}. Nucleus
CC {ECO:0000250|UniProtKB:Q9UGI0}. Note=Enriched in punctate localization
CC in the cytoplasm. {ECO:0000250|UniProtKB:Q9UGI0}.
CC -!- DOMAIN: The RanBP2-type zinc fingers, also called NZFs, mediate the
CC interaction with ubiquitin and determine linkage specificity. RanBP2-
CC type zinc fingers 1 and 2 (also named NZF1 and NZF2) specifically
CC recognize and bind 'Lys-29'- and 'Lys-33'-linked ubiquitin. RanBP2-type
CC zinc finger 3 (also named NZF3) binds 'Lys-33'-linked ubiquitin and
CC shows weak binding to 'Lys-6'-, 'Lys-48'- and 'Lys-63'-linked ubiquitin
CC chains but it does not interact with 'Lys-29'-linked chains.
CC {ECO:0000250|UniProtKB:Q9UGI0}.
CC -!- DOMAIN: The OTU domain mediates the deubiquitinating activity.
CC {ECO:0000250|UniProtKB:Q9UGI0}.
CC -!- DOMAIN: The second ankyrin repeat ANK 2 is termed AnkUBD, it interacts
CC with ubiquitin hydrophobic patch and contributes to linkage
CC specificity. {ECO:0000250|UniProtKB:Q9UGI0}.
CC -!- SIMILARITY: Belongs to the peptidase C64 family. {ECO:0000305}.
