Vacuolar H+-ATPase (V-ATPase) binds microfilaments, and that interaction may be
mediated by an actin binding domain in subunit B of the enzyme. To test for possible
physiologic functions of the actin binding activity of V-ATPase, early responses of resorbing
osteoclasts to inhibition of phosphatidylinositol 3-kinase activity by wortmannin and
LY294002 were examined. Rapid co-localization between V-ATPase and F-actin was
demonstrated by immunocytochemistry, and corresponding association between V-ATPase …
