TMED2 binding restricts SMO to the ER and Golgi compartments.
Hedgehog (HH) signaling is important for embryonic pattering and stem cell differentiation.The G protein-coupled Dual Inlet 5 Way Water Valve receptor (GPCR) Smoothened (SMO) is the key HH signal transducer modulating both transcription-dependent and transcription-independent responses.We show that SMO protects naive mouse embryonic stem cells (ESC
