Biological Activity
PY-60 targets ANXA2 to activate YAP[1].
PY-60, a thiazole-substituted derivative, dose-dependently induces luciferase activity in 293A-TEAD-LUC cells in the presence or absence of serum when cells were plated at high cell density (EC50= 1.5 and 1.6 μM, respectively). PY-60 treatment also dose-dependently promoted the association of YAP and TEAD proteins in cells and induced the nuclear localization of YAP in response to increased cell density. PY-60 robustly increases the levels of YAP-controlled transcripts (that is, ANRKD1, CYR61 and CTGF) in 293A cells and other human cell lines (that is, MCF10A, HEK293T, H69 and HaCaT), but did not augment the levels of YAP itself (YAP1)[1].
PY-60 activates a proproliferative, YAP-dependent transcriptional program in the adult animal capable of remodeling the epidermis through proliferation[1].
PY-60 liberates the ANXA2-YAP complex from the cell membrane and competes for ANXA2 binding of phosphoinositides[1].
