PYGO1 (Pygopus family PHD finger 1) is a chromatin-associated protein that functions as a coactivator in the Wnt/β-catenin signaling pathway, a critical pathway regulating embryonic development, stem cell maintenance, and cancer progression. It belongs to the Pygopus family, characterized by a conserved plant homeodomain (PHD) finger involved in recognizing histone modifications, particularly trimethylated histone H3 lysine 4 (H3K4me3), and a C-terminal homology domain for protein interactions. PYGO1 stabilizes the β-catenin/TCF transcription complex at Wnt target gene promoters, enhancing transcriptional activation.
Recombinant PYGO1 proteins are engineered in vitro using expression systems like *E. coli* or mammalian cell lines, often fused with tags (e.g., His, GST) for purification and detection. These proteins are indispensable tools for studying PYGO1’s structure-function relationships, its role in Wnt signaling dysregulation in cancers (e.g., colorectal, breast), and its interplay with chromatin modifiers like BCL9 or histone demethylases. Studies using recombinant PYGO1 have revealed its oncogenic potential, including promoting cell proliferation, metastasis, and chemoresistance. Researchers also employ it for drug screening to identify inhibitors targeting PYGO1’s PHD domain or β-catenin-binding interface. Despite progress, questions remain about its tissue-specific roles and post-translational regulation, driving ongoing interest in recombinant PYGO1 for mechanistic and therapeutic exploration.
