Ras-related protein Ral-B (RALB)

Multifunctional GTPase involved in many different cellular processes including gene expression, cell migration, cell proliferation, oncogenic transformation and membrane trafficking. Accomplishes its multiple functions by interacting with distinct downstream effectors.

Acts as a GTP detector for GTP-dependent exocytosis of dense core vesicles (By similarity). Desired both to stabilize the assembly of the exocyst complex and also to localize functional exocyst complexes into the leading edge of migrating cells (By similarity).
