Bet v 1 like

The Pfam:PF00407 entry is composed of sequences related to the major Birch (Betula verrucose) pollen antigen Bet v 1. This allergen is known to cause hayfever, dermatitis, asthma and occasionally anaphylactic shock. The other families in this clan share the same structure as Bet v 1, which is composed of antiparallel beta sheets and alpha helices. There is a cavity between the beta sheet and a long C terminal helix. The cavity appears to play roles in the binding of lipid molecules [1][2][3] which seems a common feature of the families in this clan.

This clan contains 25 families and the total number of domains in the clan is 114280. The clan was built by J Mistry.

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.
