Ovaj gen kodira člana porodice ježeva. Porodica ovih gena kodira signalne molekule koje imaju važnu ulogu u regulaciji morfogeneze. Predviđeno je da se ovaj protein tvori kao prekursor koji se cijepa autokatalizom; dio N-terminala je rastvorljiv i sadrži signalnu aktivnost, dok je dio C-terminala uključen u obradu prekursora. Što je još važnije, C-terminalni proizvod kovalentno veže holesterolski dio za N-terminalni proizvod, ograničavajući N-terminalni proizvod na ćelijsku površinu i sprečavajući ga da se slobodno širi po cijelom organizmu.
Klinički značaj
Defekti ovog proteina povezani su s djelomičnom gonadnom disgenezom (PGD), praćenom minifascikulskom polineuropatijom. Ovaj protein može biti uključen i u mušku gonadnu diferencijaciju i u perinervni razvoj.[4]
