FunFam 4: Peptidase (PNG1)

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 4 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Peptide-N4-(N-acetyl-beta-glucosaminyl)asparagine amidase activity GO:0000224
Catalysis of the reaction: 4-N-(N-acetyl-D-glucosaminyl)-protein + H2O = N-acetyl-beta-D-glucosaminylamine + peptide L-aspartate. This reaction is the hydrolysis of an N4-(acetyl-beta-D-glucosaminyl)asparagine residue in which the N-acetyl-D-glucosamine residue may be further glycosylated, to yield a (substituted) N-acetyl-beta-D-glucosaminylamine and the peptide containing an aspartic residue.

Ubiquitin-dependent glycoprotein ERAD pathway GO:0097466
An ERAD pathway whereby endoplasmic reticulum (ER)-resident glycoproteins are targeted for degradation. Includes differential processing of the glycoprotein sugar chains, retrotranslocation to the cytosol and degradation by the ubiquitin-proteasome pathway. A glycoprotein is a compound in which a carbohydrate component is covalently bound to a protein component.

1 Q55FC8 (/TAS)
Aggregation involved in sorocarp development GO:0031152
The process whose specific outcome is the progression of the aggregate over time, from its formation to the point when a slug is formed. Aggregate development begins in response to starvation and continues by the chemoattractant-mediated movement of cells toward each other. The aggregate is a multicellular structure that gives rise to the slug.
1 Q55FC8 (/IMP)
Protein deglycosylation involved in glycoprotein catabolic process GO:0035977
The removal of sugar residues from a glycosylated protein that contributes to the breakdown of a glycoprotein.
1 O74739 (/IDA)
Sorocarp spore cell differentiation GO:0044671
The process in which a relatively unspecialized cell acquires specialized features of a sorocarp spore cell, a cell of the sorocarp sorus. A sorocarp is the fruiting body characteristic of certain cellular slime moulds (e.g., Dictyosteliida) and consists of both stalk and a sorus (spore mass).
1 Q55FC8 (/IMP)
ER-associated misfolded protein catabolic process GO:0071712
The chemical reactions and pathways resulting in the breakdown of misfolded proteins transported from the endoplasmic reticulum and targeted to cytoplasmic proteasomes for degradation.

Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
