Small GTPase which cycles between active GTP-bound and inactive GDP-bound states. In its active state, binds to a variety of effector proteins to regulate homeostasis of late endocytic pathway, including endosomal positioning, maturation and secretion (PubMed:30771381). Plays a role in cytotoxic granule exocytosis in lymphocytes. Required for both granule maturation and granule docking and priming at the immunologic synapse.

RAB27A also known as ras-related protein Rab-27A is a small GTPase that plays a role in intracellular vesicle trafficking. It has a molecular mass of approximately 25 kDa. RAB27A localizes in many cell types with higher expressions in secretory cells such as melanocytes and cytotoxic T lymphocytes. It primarily functions in the regulation of vesicle docking and fusion processes with target membranes facilitating the transport of contents such as enzymes and other proteins to specific sites within the cell.
This protein regulates the exocytosis processes in certain secretory cells. RAB27A partners with effectors through its GDP-bound and GTP-bound states forming protein complexes to mediate the movement and anchoring of secretory granules. Melanocytes depend on RAB27A to control the distribution of melanosomes which are organelles containing pigment melanin. In immune cells RAB27A regulates the secretion of lytic granules significantly impacting the immune response.
This protein is involved in the melanogenesis pathway and the lytic granule exocytosis pathway. In the melanogenesis pathway RAB27A works closely with proteins such as Melanophilin and Myosin Va to control melanosome transport. In the exocytosis pathway in immune cells RAB27A interacts with proteins like UNC13D which are vital for the release of cytotoxic molecules. By controlling these pathways RAB27A influences pigment formation in skin and hair as well as immune defense mechanisms.
Mutations in the RAB27A gene are associated with Griscelli syndrome type 2 a disorder characterized by partial albinism and immune system defects. This syndrome arises from impaired melanosome transport due to dysfunctional RAB27A and its associated proteins such as Melanophilin and Myosin Va. Additionally defects in RAB27A also relate to hemophagocytic lymphohistiocytosis type 2 where impaired function in cytotoxic T lymphocytes reduces immune response effectiveness leading to excessive inflammation.
