== Function ==
[https://www.uniprot.org/uniprot/WNT8_DROME WNT8_DROME] Binds as a ligand to a family of frizzled seven-transmembrane receptors and acts through a cascade of genes on the nucleus.

== Publication Abstract from PubMed ==
Wnts are secreted growth factors that have critical roles in cell fate determination and stem cell renewal. The Wnt/beta-catenin pathway is initiated by binding of a Wnt protein to a Frizzled (Fzd) receptor and a coreceptor, LDL receptor-related protein 5 or 6 (LRP5/6). We report the 2.1 A resolution crystal structure of a Drosophila WntD fragment encompassing the N-terminal domain and the linker that connects it to the C-terminal domain. Differences in the structures of WntD and Xenopus Wnt8, including the positions of a receptor-binding beta hairpin and a large solvent-filled cavity in the helical core, indicate conformational plasticity in the N-terminal domain that may be important for Wnt-Frizzled specificity. Structure-based mutational analysis of mouse Wnt3a shows that the linker between the N- and C-terminal domains is required for LRP6 binding. These findings provide important insights into Wnt function and evolution.
