The function of DISP1 (dispatched RND transporter family member 1, ENSG00000154309) is as follows. Functions in hedgehog (Hh) signaling. Regulates the release and extracellular accumulation of cholesterol-modified hedgehog proteins and is hence required for effective production of the Hh signal (By similarity). Synergizes with SCUBE2 to cause an increase in SHH secretion (PubMed:22902404). {ECO:0000250|UniProtKB:Q3TDN0, ECO:0000269|PubMed:22902404}.
