Summary
Actin depolymerizing Factor
For motile cells such as Amoeba to move, there must be the rapid recycling of their actin cytoskeleton to enable a dynamic change in their shape. Gelsolin (PFAM:PF00626) and Cofilin (PFAM:PF00241) are two key domain families in this process. Both of these domain are structural and functional similar [1,2]. In particular, the beta sheet found at the core of the domain is structurally well conserved, with the helices that surround this sheet less conserved[2].
This clan contains 2 families and the total number of domains in the clan is 54406. The clan was built by RD Finn.

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.
