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: Arrestin_N-like (CL0135)

Summary

Arrestin_N-like Add an annotation

The families in this clan are involved in vacuolar protein trafficking, G protein signal termination and sporulation. The Arrestin N terminal domain has an Ig-like beta sandwich fold which binds to receptors and impairs their capacity to active G proteins [1]. Arrestins have also been implicated in the endocytosis of receptors and cross talk with other signalling pathways [2].

This clan contains 7 families and the total number of domains in the clan is 30167. 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.
