Plays a role in photoreceptor morphogenesis in the retina (By similarity). May maintain cell polarization and adhesion (By similarity).
Subcellular locations: Apical cell membrane, Secreted, Cell projection, Cilium, Photoreceptor outer segment, Photoreceptor inner segment
Subcellular locations: Secreted
Preferential expression in retina, also expressed in brain, testis, fetal brain and fetal eye . Expressed at the outer limiting membrane and apical to adherens junctions in the retina .
