Powering down the Pfam website
On October 5th, we began redirecting traffic from Pfam (pfam.xfam.org) to InterPro (www.ebi.ac.uk/interpro). The Pfam website will remain available at pfam-legacy.xfam.org until January 2023, when it will be decommissioned. You can read more about the sunset period in our blog post.

Clan: Chaperone-J (CL0392)


Chaperone J-domain superfamily Add an annotation

The J-domain is found in a number of stress-response proteins. It is found at the N-terminal of Hsc20, DnaJ-chaperone in E. coli, and viral large T-antigen proteins; it is also in Hsc40, mammalian auxilin and in both animal and plant DnaJ proteins. It is also found in degenerate form in Pam16 proteins.

This clan contains 2 families and the total number of domains in the clan is 94806. The clan was built by P Coggill.


This clan contains the following 2 member families:

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.
