The RAB27A antibody is a crucial tool for studying the RAB27A protein, a member of the RAS-associated binding (RAB) GTPase family involved in regulating vesicle trafficking, exocytosis, and membrane fusion. RAB27A plays key roles in diverse physiological processes, including melanosome transport in melanocytes, lytic granule secretion in cytotoxic T-cells, and platelet dense granule release. Dysregulation of RAB27A is linked to human diseases such as Griscelli syndrome type 2 (GS2), a rare autosomal recessive disorder characterized by partial albinism and immunodeficiency due to pathogenic mutations in the RAB27A gene.
RAB27A antibodies are widely used in research to investigate its expression, localization, and interactions with effector proteins like melanophilin (MLPH) and synaptotagmin-like protein (SLP). These antibodies enable detection via techniques such as Western blotting, immunofluorescence, and immunohistochemistry, aiding in studies of cellular secretion mechanisms, cancer biology (e.g., tumor exosome release), and immune dysfunction. In clinical contexts, RAB27A antibodies may assist in diagnosing GS2 and studying related pathologies, including hemophagocytic lymphohistiocytosis (HLH). Recent research also explores RAB27A's role in tumor progression, metastasis, and drug resistance, highlighting its potential as a therapeutic target. The antibody's specificity and validation across species (human, mouse, rat) make it indispensable for dissecting RAB27A-mediated pathways in both normal physiology and disease.
