Myosin-X is a member of a family of proteins called Myosins known to shuttle other molecules within the cell and thus allow their localization at the place where they are required. (europa.eu)
It is thus possible that Myosin-X shuttles molecules from the tip to the centre of the cell thus un-abling filopodia to communicate with the rest of the cell about what is detected in its environment. (europa.eu)
Attachment of Myosin-X to filaments of a molecule called actin which forms a sort of conveying belt within filopodia, is necessary for the movement of Myosin-X complexes towards the cell centre but this movement is strongly regulated by the part of Myosin-X which does not attach to actin but instead binds other molecules.
