Unconventional myosins, ie those that are not found in muscle, have the common, classical-type head domain, sometimes a neck with the IQ calmodulin-binding motifs, and then non-standard tails. These tails determine the subcellular localisation of the unconventional myosins and also help determine their individual functions. The family carries several different unconventional myosins, eg. Myo1f is expressed mainly in immune cells as well as in the inner ear where it can be associated with deafness, Myo1d has a lipid-binding module in their tail and is implicated in endosome vesicle recycling in epithelial cells. Myo1a, b, c and g from various eukaryotes are also found in this family.	Domain
