Clan: Glycine-zipper (CL0500)

Summary

Glycine-zipper TM superfamily Add an annotation

This superfamily is characterised by having long glycine-zipper motifs, characteristically GxxxGxxxG [1], often with several contiguous copies. The x following the G is frequently found to be an alanine. This sequence region can be found in both symmetric and non-symmetrical membrane structures, and is relatively common. The fact that such a large fraction of the relatively few known membrane channel structures use the glycine zipper suggests that the sequence motif plays a special role in forming these homo-oligomeric bundles [1].

This clan contains 5 families and the total number of domains in the clan is 7226. The clan was built by P Coggill.
