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: SPOC (CL0616)

Summary

SPOC domain-like superfamily Add an annotation

The crystal structure of the SPOC domain [3] showed it has similarity with the beta barrel domain of the Ku proteins. These domains share a 7 stranded beta barrel. In the Ku proteins this domain interacts DNA, whereas the SPOC domain mediates protein binding.

This clan contains 4 families and the total number of domains in the clan is 13621. The clan was built by A Bateman.

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.
