Background: Wnt proteins are rich in cysteines, but their functional significance has not been systematically examined.Results: Mutagenesis of cysteines in Wnt3a uncovers their requirements for Wnt secretion and/or receptor binding.Conclusion: Behaviors of the Wnt3a cysteine mutants are consistent with the Wnt structure model.Significance: This study provides insights into pathogenesis associated with WNT mutations and new tool sets for WNT research.
