Abnormal intermediate filament organization alters mitochondrial motility in giant axonal neuropathy fibroblasts.

abstract：:We identified a novel interaction between myosin VI and the GLUT1 transporter binding protein GLUT1CBP(GIPC1) and first proposed that as an adapter molecule it might function to couple vesicle-bound proteins to myosin VI movement. This study refines the model by identifying two myosin VI binding domains in the GIPC1 C...
