FAMILY

G-protein coupled receptor Fz/Smo family

DESCRIPTION

Also known as SMO_HUMAN, SMO, SMOH. G protein-coupled receptor that probably associates with the patched protein (PTCH) to transduce the hedgehog's proteins signal. Binding of sonic hedgehog (SHH) to its receptor patched is thought to prevent normal inhibition by patched of smoothened (SMO). Required for the accumulation of KIF7, GLI2 and GLI3 in the cilia (PubMed:19592253). Interacts with DLG5 at the ciliary base to induce the accumulation of KIF7 and GLI2 at the ciliary tip for GLI2 activation (By similarity). Homodimer (PubMed:23636324). Interacts with ARRB2 (By similarity). Interacts with KIF7 (PubMed:19592253). Interacts with BBS5 and BBS7; the interactions are indicative for the association of SMO with the BBsome complex to facilitate ciliary localization of SMO (PubMed:22072986). Interacts with DLG5 and SDCBP (By similarity). Interacts with GAS8/DRC4 (PubMed:21659505).
