Myosin-Vb is a protein that in humans is encoded by the MYO5B gene.[1][2][3]

Recent evidence suggests that Myosin VB is related to the creation of memories[4] by actin-dependent trafficking of AMPA receptor containing recycling endosomes in dendritic spines.[5]

Mutations of MYO5B cause microvillus inclusion disease[6] and have been associated with bipolar disorder.[7]


MYO5B has been shown to interact with RAB11FIP2.[8]
