| membrane bound, colocalizing with melanosomes |
basic FUNCTION
| being a small GTPase, key effector of cytotoxic granule exocytosis, vesicle transport and organelles dynamics, targeting transport and fusion of vesicles with their appropriate membrane acceptors |
|
RAB27A, MYRIP and MYO7A bridges retinal melanosomes to the actin cytoskeleton and thereby mediates the local trafficking of these organelles ![](pubmed.jpg) |
|
involved in the transport of melanosomes to the cell periphery |
|
involved in other fundamental physiological functions, such as the transport of lytic granules and insulin secretion |
|
required for both granule maturation and granule docking and priming at the immunologic synapse ![](pubmed.jpg) |
|
involved in terminal phases of cytotoxic granule/melanosome exocytosis ![](pubmed.jpg) |
