Myosin-Viia (ck) Drosophila Melanogaster Recombinant Protein

Myosins are actin-based motor molecules with ATPase activity (PubMed:16585515). Unconventional myosins serve in intracellular movements: can function in cells as a single-molecule cargo transporter (PubMed:16585515). A very slow and high-duty-ratio motor, may be suitable for tension maintenance of actin filaments (PubMed:16585515). Their highly divergent tails are presumed to bind to membranous compartments, which would be moved relative to actin filaments (PubMed:15579689). Plays a key role in the formation of cellular projections and other actin-based functions required for embryonic and larval viability (PubMed:15579689, PubMed:16585515). Necessary for auditory transduction: plays a role in Johnston's organ organization by functioning in scolopidial apical attachment and therefore to acoustic stimulus propagation from the antenna a2/a3 joint to transducing elements (PubMed:15886106, PubMed:27331610). Interaction with the myosin zip may be important for its function in scolopidial apical attachment (PubMed:27331610). During oogenesis it has Cad99c-dependent and Cad99c-independent roles in regulating the shape and spacing of the follicle cell microvilli which secrete eggshell material such as the vitelline membrane (PubMed:25236597). May be required for the normal expression of Cad99c in the follicle cell microvilli (PubMed:25236597).
