| Tissue Specificity | Isoform A: Expressed in small intestine, kidney, pancreas, placenta as well as in retina. Weaker expression in lung, liver and heart. Not expressed in brain and skeletal muscle. Isoform B: Expressed only in the retina. Isoform 3: Ubiquitously expressed. |
| Function | Potentially involved in docking of synaptic vesicles at presynaptic active zones. Apical receptor involved in membrane fusion of apical vesicles. Isoform B: Essential for survival of retinal photoreceetors. Isoform 3: Functions as a regulator of gene expression. |
