Tubby-related protein 1 (TULP1)

Required for normal development of photoreceptor synapses. Required for normal photoreceptor function and for long- term survival of photoreceptor cells.

Interacts with cytoskeleton proteins and might play a role in protein transport in photoreceptor cells (By similarity). Binds lipids, especially phosphatidylinositol 3-phosphate, phosphatidylinositol 4- phosphate, phosphatidylinositol 5-phosphate, phosphatidylinositol 3,4-bisphosphate, phosphatidylinositol 4,5-bisphosphate, phosphatidylinositol 3,4,5-bisphosphate, phosphatidylserine and phosphatidic acid (in vitro).
