Clan: APCOP-app_sub (CL0545)


Clathrin (AP) and COPI appendage platform subdomain Add an annotation

This superfamily is characterised by subdomains from the clathrin and coatomer appendages. The superfamily possesses a single protein/protein interaction site that in yeast binds to the ARFGAP Glo3p, and in mammalian gamma-COP binds to a Glo3p orthologue, ARFGAP2 [1].

This clan contains 4 families and the total number of domains in the clan is 2225. The clan was built by P Coggill.

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.
