Summary
JAB-like superfamily
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.
This clan contains 7 families and the total number of domains in the clan is 31417. The clan was built by A BatemanLM IyerD Zhang and L Aravind.

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 MSD group, to allow us to map Pfam domains onto UniProt three-dimensional structures. The table below shows the mapping between the Pfam families in this clan, the corresponding UniProt entries, and the region of the three-dimensional structures that are available for that sequence.
