Minus-end microtubule-dependent motor protein. Involved in apically targeted transport. Required for zonula adherens maintenance. Interacts with annexin XIIIB. Localizes along zonula adherens only at mature cell-cell contacts (By similarity). Apical cell membrane. On membrane organelles immediately beneath the apical plasma membrane of renal tubular epithelial cells. Localized in the distal tubules and loops of Henle in the kidney, but not in the proximal tubules or the glomeruli, with stronger staining in the apical area of these epithelial cells. Predominant expression in the kidney, testis and ovary. Also expressed in brain, heart, liver, lung and uterus. Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family.
