The tumor antigen 5T4/WAIF1 (Wnt-activated inhibitory factor 1; also known as Trophoblast glycoprotein TPBG) is a cell surface protein targeted in multiple cancer immunotherapy clinical trials. Recently, it has been shown that 5T4/WAIF1 inhibits Wnt/beta-catenin signaling, a signaling system central to many developmental and pathological processes. Wnt/beta-catenin signaling is controlled by multiple inhibitors and activators. Here, we report crystal structures for the extracellular domain of 5T4/WAIF1 at 1.8 A resolution. They reveal a highly glycosylated, rigid core, comprising eight leucine-rich repeats (LRRs), which serves as a platform to present evolutionarily conserved surface residues in the N-terminal LRR1. Structural and cell-based analyses, coupled with previously reported in vivo data, suggest that Tyr325 plus the LRR1 surface centered on a second exposed aromatic residue, Phe97, are essential for inhibition of Wnt/beta-catenin signaling. These results provide a structural basis for the development of 5T4/WAIF1-targeted therapies that preserve or block 5T4/WAIF1-mediated inhibition of Wnt/beta-catenin signaling.
