Summary
Calponin homology domain
The calponin homology (CH) domain is found in a variety of contexts, ranging from proteins involved in signalling pathways to cytoskeletal proteins. They seem to have diverse cellular functions, which are thought to include actin binding, involvement in the MAP kinase signalling pathway, and regulation of GEF activity in Rho family GTPase pathways. Structurally, they are organised into three layers, with two parallel alpha helices in the core being sandwiched between another two helices, one on each side [1].
This clan contains 9 families and the total number of domains in the clan is 93243. The clan was built by M Fenech.

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.
