CC -!- FUNCTION: Myosin heavy chain that is required for the cell cycle-
CC regulated transport of various organelles and proteins for their
CC segregation. Functions by binding with its tail domain to receptor
CC proteins on organelles and exerting force with its N-terminal motor
CC domain against actin filaments, thereby transporting its cargo along
CC polarized actin cables (By similarity). Involved in endocytosis via its
CC action in endosomal trafficking. {ECO:0000250,
CC ECO:0000269|PubMed:18393384}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell junction, plasmodesma. Endosome.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=1;
CC Comment=A number of isoforms are produced. According to EST
CC sequences.;
CC Name=1;
CC IsoId=F4K0A6-1; Sequence=Displayed;
CC -!- TISSUE SPECIFICITY: Expressed in flowers, leaves and roots.
CC {ECO:0000269|PubMed:7811972}.
CC -!- DOMAIN: IQ domain mediates interaction with calmodulin. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the TRAFAC class myosin-kinesin ATPase
CC superfamily. Myosin family. Plant myosin class VIII subfamily.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAB10751.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
CC Sequence=CAA84065.1; Type=Frameshift; Evidence={ECO:0000305};
