Clan: Tetraspannin (CL0347)

Summary

Tetraspannin-like Add an annotation

This clan includes the tetraspanin family which contains four transmembrane regions. The CD20 family also has four transmembrane regions, but its members are not considered true tetraspanins as they lack nearly all of the key functional tetraspanin residues [1].

This clan contains 3 families and the total number of domains in the clan is 6471. The clan was built by J Mistry and 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.
