PY-60 is a robust and specific activator ofYAPtranscriptional activity that targetsannexin A2 (ANXA2)with aK_dof 1.4 μM. PY-60 directly binds to ANXA2 and antagonizes its normal cellular function of repressingYAPactivity^[1].

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,CYR61andCTGF) 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].

PY-60 (10 uM; applied topically to the dorsal skin of wild-type adult C57BL/6 mice over the course of 10 days) promotes a dramatic expansion of keratinocytes and K14-positive precursors, as assessed by hematoxylin and eosin and anti-K14 histological staining at the study end. PY-60 results in an approximate doubling of epidermal thickness, a result derived from an increased number of keratinocytes per unit length of skin^[1].
