Functional Families

Overview of the Structural Clusters (SC) and Functional Families within this CATH Superfamily. Clusters with a representative structure are represented by a filled circle.

Superfamily: Wnt, WIF domain

Wnt morphogens control embryonic development and homeostasis in adult tissues. In vertebrates the N-terminal WIF domain (WIF-1WD) of Wnt inhibitory factor 1 (WIF-1) binds Wnt ligands.

This superfamily entry represents the WIF domain, it is found in the RYK tyrosine kinase receptors and WIF the Wnt-inhibitory-factor. The domain is extracellular and contains two conserved cysteines that may form a disulphide bridge. This domain is Wnt binding in WIF, and it has been suggested that RYK may also bind to Wnt PMID:10637605. The WIF domain of WIF-1 was suggested to have a function in inhibiting Wnt signalling PMID:21743455.
