Myosin V uses

Myosin V can have multiple functions in a single cell. For example in budding yeast Myosin V through binding various adaptor proteins can transport to the growing bud membrane cargoes, microtubules and specific mRNAs. Myosin V mediates the asymmetric segregation of the ash1 mRNA in budding yeast. Ash1p protein ensures that only the mother cell changes mating type. ash1 mRNA is tethered to Myosin V through adaptor proteins, She2 and She3. Actin filaments are nucleated at the bud tip by formin. Myosin V travels towards the the plus end of actin filaments bringing ash1 mRNA with it. ash1 mRNA is only translated in the bud cell to prevent differentiation.
