Gen se nalazi na dugom kraku hromosoma 2 (2q37.1). Kodirani protein je dug 603 aminokiselinska ostatka sa predviđenom molekulskom težinom od 64.597 daltona.

Protein sadrži domen peptidaze S1 i ima tripsinsku aktivnost poput serin-proteaze.

Mutacije ovog gena uzrokuju autosomno recesivni stražnji mikroftalmus.^[6]^[7]^[8] Kliničke karakteristike ovog stanja uključuju ekstremnu hiperopiju, zbog kratke aksijalne dužine sa suštinski normalnim prednjim segmentom, strme zakrivljenosti rožnjača, plitku prednju komoru, debela sočiva i zadebljane zidove sklere. Palpebralne pukotine izgledaju uske zbog relativno duboko postavljenih očiju. Oštrina vida je blago do umjereno smanjena, a česta je anizometropska ili strabizamska ambliopija. Fundus oka pokazuje pretrpane optičke diskove, krivudave sudove i abnormalnu avaskularnu zonu fovea.

Homozigotni miševi za mutaciju izazvanu ENU pokazuju povećan unutaročni pritisak, smanjenje aksijalne dužine oka i uske iridorožnjačne uglove. Oči osoba sa glaukomom zatvorenog ugla (ACG) često imaju skromno smanjenu aksijalnu dužinu, plitku prednju komoru i relativno veliko sočivo, karakteristike koje predisponiraju zatvaranju kuta. Homozigotni miševi model ACG.^[7]
