Domain (CC)
The N-terminal extracellular domain mediates sterol-binding which is required for maximal activation of signaling (PubMed:24859340). Contains a second sterol-binding site within the seven-transmembrane pocket which is also required for activation (By similarity). The activating sterol is likely to be cholesterol (PubMed:35658032). The extracellular site is required for SHH-induced activity while the site within the transmembrane pocket regulates basal signaling in the absence of SHH (PubMed:35658032).
