Summary: JAB1/Mov34/MPN/PAD-1 ubiquitin protease
Pfam includes annotations and additional family information from a range of different sources. These sources can be accessed via the tabs below.
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
This tab holds the annotation information that is stored in the Pfam database. As we move to using Wikipedia as our main source of annotation, the contents of this tab will be gradually replaced by the Wikipedia tab.
JAB1/Mov34/MPN/PAD-1 ubiquitin protease Provide feedback
Members of this family are found in proteasome regulatory subunits, eukaryotic initiation factor 3 (eIF3) subunits and regulators of transcription factors. This family is also known as the MPN domain [3] and PAD-1-like domain [4] JABP1 domain [5] or JAMM domain [7]. These are metalloenzymes that function as the ubiquitin isopeptidase/ deubiquitinase in the ubiquitin-based signalling and protein turnover pathways in eukaryotes [7]. Versions of the domain in prokaryotic cognates of the ubiquitin-modification pathway are shown to have a similar role, and the archael protein from Haloferax volcanii is found to cleave ubiquitin-like small archaeal modifier proteins (SAMP1/2) from protein conjugates [8,9].

InterPro entry 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 ].

Pfam Clan
This family is a member of clan JAB (CL0366), which has the following description:
This superfamily includes a number of proteasome regulatory subunits, eukaryotic initiation factor 3 (eIF3) subunits, regulators of transcription factors and ubiquitination-assisting protein families. In eukaryotes and in prokaryotic cognates of the ubiquitin-based modification pathway, they function as ubiquitin isopeptidases/ deubiquitinases. JAB domains are also found in diverse metabolic pathways in prokaryotes such as siderophore and cysteine biosynthesis. Other distinct versions of the JAB domain, such as RadC are predicted to function as nucleases. Structurally, the JAB domain is related to the nucleotide deaminase and binds a Zinc ion in a similar structural location.
The clan contains the following 7 members:

We store a range of different sequence alignments for families. As well as the seed alignment from which the family is built, we provide the full alignment, generated by searching the sequence database (reference proteomes) using the family HMM. We also generate alignments using four representative proteomes (RP) sets and the UniProtKB sequence database. More...
View options
We make a range of alignments for each Pfam-A family. You can see a description of each above. You can view these alignments in various ways but please note that some types of alignment are never generated while others may not be available for all families, most commonly because the alignments are too large to handle.

Trees
This page displays the phylogenetic tree for this family's seed alignment. We use FastTree to calculate neighbour join trees with a local bootstrap based on 100 resamples (shown next to the tree nodes). FastTree calculates approximately-maximum-likelihood phylogenetic trees from our seed alignment.
Note: You can also download the data file for the tree.

Structures
For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the JAB domain has been found. There are 294 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein sequence.
