A myosin complex containing a dimer of class XI myosin heavy chains and associated light chains. Myosin XI heavy chain sizes are similar in molecular structure to the class V myosins with 5 to 6 IQ motifs and tail regions with predicted coiled coil domains (forming dimeric molecules) and large C-terminal regions.
