Protein kinase C regulates alpha v beta 5-dependent cytoskeletal associations and focal adhesion kinase phosphorylation
Integrins alpha v beta 3 and alpha v beta 5 both mediate cell adhesion to vitronectin yet trigger different postligand binding events. Integrin alpha v beta 3 is able to induce cell spreading, migration, angiogenesis, and tumor metastasis without additional stimulators, whereas alpha v beta 5 requires exogenous activation of protein kinase C (PKC) to mediate these processes. To investigate this...
متن کاملProtein Kinase C Regulates v[35-dependent Cytoskeletal Associations and Focal Adhesion Kinase Phosphorylation
Integrins av[33 and av[35 both mediate cell adhesion to vitronectin yet trigger different postligand binding events. Integrin av133 is able to induce cell spreading, migration, angiogenesis, and tumor metastasis without additional stimulators, whereas av135 requires exogenous activation of protein kinase C (PKC) to mediate these processes. To investigate this difference, the ability of 133 or 1...
متن کاملProtein kinase C involvement in focal adhesion formation.
Matrix molecules such as fibronectin can promote cell attachment, spreading and focal adhesion formation. Although some interactions of fibronectin with cell surface receptors have now been identified, the consequent activation of intracellular messenger systems by cell/matrix interactions have still to be elucidated. We show here that the kinase inhibitors H7 and HA1004 reduce focal adhesion a...
متن کاملDomain structure and phosphorylation of protein kinase C.
The phospholipid- and calcium-dependent protein kinase C has been shown to autophosphorylate on both the catalytic and the regulatory domains. The autophosphorylation displays zero-order kinetics, indicating that it is an intramolecular event. Autophosphorylation increases the activity of protein kinase C by decreasing the Km for the substrate H1 histone. The catalytic fragment obtained by limi...
متن کاملCarboxyl-terminal phosphorylation regulates the function and subcellular localization of protein kinase C betaII.
Protein kinase C is processed by three phosphorylation events before it is competent to respond to second messengers. Specifically, the enzyme is first phosphorylated at the activation loop by another kinase, followed by two ordered autophosphorylations at the carboxyl terminus (Keranen, L. M., Dutil, E. M., and Newton, A. C. (1995) Curr. Biol. 5, 1394-1403). This study examines the role of neg...
