The conserved Hedgehog signaling pathway is essential for embryonic development and tissue homeostasis and is tightly regulated. In this issue of Developmental Cell, Ma et al. (2016) demonstrate that sumoylation works in parallel with phosphorylation to stabilize Smoothened, antagonizing its ubiquitination and subsequent degradation, thus activating Hh target gene transcription.
