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: Tubulin (CL0566)


Tubulin nucleotide-binding domain-like, GTPase Add an annotation

The characteristic families of this clan are the tubulin GTPase domain and the alpha and beta tubulin subunits. A segmental duplication early on in the primate lineage has led to the creation of up to three tubulin-like domains in the higher primates. The most N-terminal one is the Misato domain, which probably represents the original domain [3].

This clan contains 4 families and the total number of domains in the clan is 35387. The clan was built by P Coggill.

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.
