Clan: Bet_V_1_like (CL0209)

Summary

Bet V 1 like Add an annotation

The Bet_V_I family is composed of sequences related to the major Birch (Betula verrucose) pollen antigen Betv1. This allergen is known to cause hayfever, dermatitis, asthma and occasionally anaphylactic shock. The other families in this clan share the same structure as Betv1 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 14 families and the total number of domains in the clan is 23609. The clan was built by J Mistry.

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.
