Summation

GPA3 encodes a plant-specific kelch-repeat protein localized to the trans-Golgi networks, Golgi-derived dense vesicles (DVs), and protein storage vacuoles in rice developing endosperm. OsGPA3 directly interacts with the rice Rab5a-guanine exchange factor VPS9a and forms a regulatory complex with Rab5a via VPS9a to regulate DV-mediated post-Golgi trafficking of major storage proteins in rice endosperm during grain filling and maturation (Ren et al., 2014).
