VBS-like four-helical bundle superfamily

This superfamily groups families with the conserved four or five-helix up-and-down bundle structure which is conserved and typical of focal adhesion targeting (FAT) domains. This structure is responsible for dimerisation, being also present in transcriptional regulators in which it is important for their dynamic conformational equilibrium to control the target specificity.

This clan contains 9 families and the total number of domains in the clan is 22659. The clan was built by S Chuguransky and A Bateman.

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.
