Neurexins are cell adhesion molecules involved in synapse formation and synaptic regulation. Mutations in theneurexingenes are linked to a number of neurodevelopmental disorders such as autism. Here, we show that theDrosophilahomolog of α-Neurexin is critical for fly visual function. Lack of Neurexin leads to significantly impaired visual function due to reduced rhodopsin levels. We show that the decreased chromophore levels cause deficits in rhodopsin maturation and that Neurexin is required for retinoid transport. Using yeast two-hybrid screening, we identify that Neurexin interacts with apolipoprotein I (ApoL I), a product generated by cleavage of retinoid- and fatty acid-binding glycoprotein (RFABG) that functions in retinoid transport. Finally, we demonstrate that Neurexin is essential for the apolipoproteins level. Our results reveal a role for Neurexin in mediating retinoid transport and subsequent rhodopsin maturation and suggest that Neurexin regulates lipoprotein function.
