GRK2 Kinases in the Primary Cilium Initiate SMOOTHENED-PKA Signaling in the Hedgehog Cascade

M. F. Walker, J. Zhang, W. Steiner, P.-I. Ku, J.-F. Zhu, Z. Michaelson, Y.-C. Yen, A. Lee, A. B. Long, M. J. Casey, A. Poddar, I. B. Nelson, C. D. Arveseth, F. Nagel, R. Clough, , B. R. Myers

This study identifies GRK2-mediated phosphorylation of SMO in the primary cilium as a critical step initiating SMO-PKA signaling in the Hedgehog pathway.

A PKA Inhibitor Motif within Smoothened Controls Hedgehog Signal Transduction

J. T. Happ, C. D. Arveseth, J. Bruystens, D. Bertinetti, I. B. Nelson, C. Olivieri, D. S. Hedeen, J.-F. Zhu, J. L. Capener, J. W. Bröckel, L. Vu, C. C. King, V. L. Ruiz-Perez, G. Veglia, F. W. Herberg, , B. R. Myers

This study identifies a PKA inhibitor motif in Smoothened that blocks PKA activity, enabling GLI activation in the Hedgehog pathway, revealing a mechanism similar to the Wnt cascade.

Smoothened Transduces Hedgehog Signals via Activity-Dependent Sequestration of PKA Catalytic Subunits

C. D. Arveseth, J. T. Happ, D. S. Hedeen, J.-F. Zhu, J. L. Capener, D. K. Shaw, I. Deshpande, J. Liang, J. Xu, S. L. Stubben, I. B. Nelson, M. F. Walker, N. J. Krogan, D. J. Grunwald, R. Hüttenhain, , B. R. Myers

This study reveals that Smoothened (SMO) activates GLI transcription factors by sequestering PKA catalytic subunits at the membrane, bypassing traditional GPCR signaling mechanisms.
