Summary
Cystine-knot cytokine superfamily
The cytokine families in this clan have the cystine-knot fold. In this 6 cysteines form three disulphide bridges that are interlinked.
This clan contains 14 families and the total number of domains in the clan is 28387. 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.
