PHD finger found in Drosophila melanogaster protein pygopus (dPYGO) and similar proteins
dPYGO, also termed protein gammy legs, is a nuclear adapter protein encoded by pygopus (pygo). It is a fundamental Wnt signaling transcriptional component in Drosophila, and has both Wnt-related and Wnt-independent functions. It plays a critical role in aging-related cardiac dysfunction that is canonical Wnt signaling independent. dPYGO contains a plant homeodomain (PHD) finger, which is important for Lgs/Bcl9 recognition as well as for the regulation of the Wnt/beta-catenin signaling pathway.
