Interpro abstract (IPR000555):

This domain is known as the MPN domain [ (PUBMED:9644972) ], PAD-1-like domain [ (PUBMED:10369758) ], JABP1 domain [ (PUBMED:20838651) ] or JAMM domain [ (PUBMED:12183636) ]. Proteins with this domain include proteasome regulatory subunits, eukaryotic initiation factor 3 (eIF3) subunits and regulators of transcription factors. They are metalloenzymes that function as the ubiquitin isopeptidase/ deubiquitinase in the ubiquitin-based signaling and protein turnover pathways in eukaryotes [ (PUBMED:12183636) ]. Versions of the domain in prokaryotic cognates of the ubiquitin-modification pathway are predicted to have a similar role [ (PUBMED:16859499) ].

The archaeal (H. volcanii) JAMM domain containing protein, HvJAMM1, cleaves ubiquitin-like small archaeal modifier proteins (SAMP1/2) from protein conjugates [ (PUBMED:22970855) ]. The bacterial JAMM domain containing protein QbsD from Pseudomonas fluorescens cleaves the C-terminal amino acid residues of the sulfur carrier protein QbsE prior to the formation of the carboxy-terminal thiocarboxylate [ (PUBMED:17209031) ].

GO function:metallopeptidase activity (GO:0008237), protein binding (GO:0005515), isopeptidase activity (GO:0070122)
