MYO7B (Myosin VIIB) is a member of the myosin motor protein superfamily, which plays critical roles in intracellular transport, cytoskeletal organization, and mechanotransduction. As an actin-based motor protein, MYO7B utilizes ATP hydrolysis to generate force and movement along actin filaments. It is structurally characterized by a conserved motor domain responsible for actin binding and ATPase activity, followed by a tail region containing specific protein-protein interaction motifs. This unique architecture enables MYO7B to participate in specialized cellular processes, particularly in polarized epithelial cells.
Research has linked MYO7B to hearing function and intestinal homeostasis. In the inner ear, it contributes to hair cell maintenance and stereocilia organization, with mutations associated with hereditary hearing loss in animal models. In the gastrointestinal tract, MYO7B localizes to microvilli of enterocytes, where it interacts with scaffolding proteins to regulate microvillar structure and function. Studies suggest its involvement in vesicle trafficking and membrane remodeling at apical surfaces, crucial for nutrient absorption and barrier integrity. MYO7B dysfunction has been implicated in intestinal disorders like microvillus inclusion disease.
Recombinant MYO7B protein is engineered for in vitro studies, typically produced in bacterial or mammalian expression systems. This purified tool enables biochemical characterization of its motor activity, binding partners, and regulatory mechanisms. Researchers use it to investigate molecular defects caused by disease-associated mutations and to screen potential therapeutic compounds. Its application extends to structural studies using cryo-EM and X-ray crystallography, advancing our understanding of myosin mechanics. As a key player in epithelial cell biology, recombinant MYO7B remains valuable for unraveling its physiological roles and pathophysiological contributions.
