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.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThis 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.\u003cbr\u003e\nPathways\u003cbr\u003e\nThis 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.\u003cbr\u003e\nMutations 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.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46845025190057,"sku":"ab55667","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab55667","provider":"Iright","version":"1.0","type":"link"}
