Predicted to enable phosphatidylinositol-3,4-bisphosphate binding activity and phospholipid binding activity. Predicted to be involved in protein homooligomerization and visual perception. Predicted to act upstream of or within adaptation of rhodopsin mediated signaling and retina layer formation. Predicted to be located in extracellular space; neuron to neuron synapse; and photoreceptor inner segment. Predicted to be extrinsic component of plasma membrane. Human ortholog(s) of this gene implicated in X-linked juvenile retinoschisis 1 and retinoschisis. Orthologous to human RS1 (retinoschisin 1). [provided by Alliance of Genome Resources, Apr 2022]
