CC -!- FUNCTION: Specifically deglycosylates the denatured form of N-linked
CC glycoproteins in the cytoplasm and assists their proteasome-mediated
CC degradation (PubMed:17509531, PubMed:17522090). Cleaves the beta-
CC aspartyl-glucosamine (GlcNAc) of the glycan and the amide side chain of
CC Asn, converting Asn to Asp (PubMed:17522090). Prefers proteins
CC containing high-mannose over those bearing complex type
CC oligosaccharides (PubMed:17522090). Can recognize misfolded proteins in
CC the endoplasmic reticulum that are exported to the cytosol to be
CC destroyed and deglycosylate them, while it has no activity toward
CC native proteins (PubMed:17509531). Deglycosylation is a prerequisite
CC for subsequent proteasome-mediated degradation of some, but not all,
CC misfolded glycoproteins (PubMed:17509531). Also displays oxidoreductase
CC (thioredoxin) activity (PubMed:17509531, PubMed:17522090). Involved in
CC regulating the expression of proteasomal subunits such as rpt-3 in
CC order to confer resistance to proteasomal dysfunction
CC (PubMed:27528192). {ECO:0000269|PubMed:17509531,
CC ECO:0000269|PubMed:17522090, ECO:0000269|PubMed:27528192}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of an N(4)-(acetyl-beta-D-glucosaminyl)asparagine
CC residue in which the glucosamine residue may be further glycosylated,
CC to yield a (substituted) N-acetyl-beta-D-glucosaminylamine and a
CC peptide containing an aspartate residue.; EC=3.5.1.52;
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC -!- ACTIVITY REGULATION: Inhibited by Zn(2+) and z-VAD-fmk (caspase
CC inhibitor) but unaffected by EDTA. {ECO:0000269|PubMed:17522090}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:17522090}.
CC Endoplasmic reticulum {ECO:0000269|PubMed:17522090}. Note=ER
CC localization inferred from partial colocalization with an ER marker,
CC membrane protein PIG-X.
CC -!- DISRUPTION PHENOTYPE: Double knockout with rpt-5 RNAi results in failed
CC expression of the proteasomal subunit rpt-3.
CC {ECO:0000269|PubMed:27528192}.
CC -!- SIMILARITY: Belongs to the transglutaminase-like superfamily. PNGase
CC family. {ECO:0000255|PROSITE-ProRule:PRU00731}.
