MYO19 is an unconventional myosin, a class of actin-based motor proteins involved in intracellular transport and organelle dynamics. Belonging to the myosin XIX family, it is distinct from conventional myosins due to its unique structural features and specialized roles. MYO19 is primarily localized to mitochondria, where it regulates mitochondrial motility, distribution, and network integrity. Its motor domain binds actin filaments, enabling force generation, while its tail domain contains mitochondria-targeting sequences and coiled-coil regions for oligomerization and cargo interaction.
Recombinant MYO19 proteins are engineered to study its molecular mechanisms and interactions. These proteins are typically expressed in heterologous systems (e.g., bacterial, insect, or mammalian cells) and purified for in vitro assays. Key applications include analyzing ATPase activity, actin-binding kinetics, and mitochondrial trafficking in reconstituted systems. Researchers also use MYO19 truncations or tagged variants (e.g., GFP-fusions) to map functional domains or visualize real-time mitochondrial dynamics in live cells.
MYO19 dysfunction is linked to mitochondrial fragmentation, impaired cell migration, and metabolic stress, implicating it in diseases like cancer, neurodegenerative disorders, and metabolic syndromes. Recombinant MYO19 tools aid in screening small molecules targeting mitochondrial motility or testing gene therapies. Recent studies highlight its role in mitochondrial DNA segregation and apoptosis regulation, expanding its therapeutic relevance. Despite progress, questions remain about its precise regulatory pathways and tissue-specific functions, driving ongoing demand for optimized recombinant MYO19 constructs in mechanistic and translational studies.
