FunctionProcessive actin-based motor that can move in large steps approximating the 36-nm pseudo-repeat of the actin filament. Involved in melanosome transport. Also mediates the transport of vesicles to the plasma membrane. May also be required for some polarization process involved in dendrite formation.
Tissue specificityDetected in melanocytes.
Involvement in diseaseGriscelli syndrome 1 Griscelli syndrome 3 Elejalde syndrome
