Protein: Myosin-9 (Myosin XI C) (AtXIC) (F4HXP9)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Myosin heavy chain that is required for the cell cycle-regulated transport of various organelles and proteins for their segregation. Functions by binding with its tail domain to receptor proteins on organelles and exerting force with its N-terminal motor domain against actin filaments, thereby transporting its cargo along polarized actin cables. Involved in trafficking of Golgi stacks and mitochondria.
