Powering down the Pfam website
On October 5th, we began redirecting traffic from Pfam (pfam.xfam.org) to InterPro (www.ebi.ac.uk/interpro). The Pfam website will remain available at pfam-legacy.xfam.org until January 2023, when it will be decommissioned. You can read more about the sunset period in our blog post.

Clan: Chemosens_recp (CL0176)


Chemosensory 7tm receptor superfamily Add an annotation

The members of this clan are families of various gustatory and odorant receptors. They are described as being seven-transmembrane receptors, and in fact all show characteristic regions of hydrophobicity on the alignment.

This clan contains 4 families and the total number of domains in the clan is 15196. The clan was built by R Finn and M Fenech.


This clan contains the following 4 member families:

7tm_6 7tm_7 DUF267 Trehalose_recp

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.
