Key result
The globular tail of plant myosin XI shares a similar structure with yeast myosin V but has evolved plant-specific cargo binding mechanisms where either subdomain alone is targeting-competent.
The study identifies that the globular tail of plant myosin XI has evolved specific cargo binding mechanisms distinct from animal/fungal myosin V, with separate subdomains capable of independent organelle targeting.

Does not alter clinical practice; extends myosin evolution insights but leaves open mammalian translation.
Li et al. (2007) studied this question. Myosin XI globular tail subdomain interaction analysis was evaluated on Organelle targeting and subdomain interaction. The globular tail of plant myosin XI shares a similar structure with yeast myosin V but has evolved plant-specific cargo binding mechanisms where either subdomain alone is targeting-competent.
