Generic protein structure example

Myosin-Vb, a myosin V type protein, is encoded by the MYO5B gene in humans.[1][2][3][4]

Recent evidence suggests that Myosin-Vb is related to the creation of memories[5] by actin-dependent trafficking of AMPA receptor containing recycling endosomes in dendritic spines.[6]

Mutations of MYO5B cause microvillus inclusion disease due to defective trafficking of apical and basolateral proteins.[4]

MYO5B has also been associated with bipolar disorder.[7]

Interactions

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