Congrats to @labogden.bsky.social on their important new work on how arachidonic acid regulates Smoothened to tune Hedgehog signaling!
Interestingly, mutating the pocket selectively impairs cardiopulmonary development.
Could AA+oxysterol be the endogenous SMO ligand?

Receptor allostery promotes context-specific Sonic Hedgehog signaling during embryonic development - Nature Communications
Here, they identify a binding site on the Sonic Hedgehog signaling protein Smoothened for the allosteric regulator arachidonic acid (AA). A mutation that disrupts AA binding to this pocket compromises...
