CC -!- FUNCTION: Involved in directing the movement of organelles along actin
CC filaments. {ECO:0000305}.
CC -!- PTM: Phosphorylated by ALPK1. {ECO:0000250|UniProtKB:Q9UBC5}.
CC -!- SIMILARITY: Belongs to the TRAFAC class myosin-kinesin ATPase
CC superfamily. Myosin family. {ECO:0000305}.
CC -!- CAUTION: Represents an unconventional myosin. This protein should not
CC be confused with the conventional myosin-1 (MYH1). {ECO:0000305}.
