Rin3 - Ras and Rab interactor 3

Predicted to enable guanyl-nucleotide exchange factor activity and small GTPase binding activity. Predicted to be involved in regulation of catalytic activity; signal transduction; and vesicle-mediated transport. Predicted to act upstream of or within negative regulation of receptor internalization and regulation of vesicle size. Predicted to be located in several cellular components, including cytoplasmic vesicle; dendrite; and neuronal cell body. Orthologous to human RIN3 (Ras and Rab interactor 3).
