Question Answer
When T.K is phosphorylated, which subunit of PI-3-Kinase binds first? P85
What allows the regulatory subunit to bind? The Sh2 domain
Name the catalytic subunit of PI-3-Kinase p110
When PI-3-Kinase is complete, what binds? Activated RAS
Role 1 of PI-3-Kinase Phosphorylation if PIP2 to PIP3
Part of PDK1 that allows PIP3 interaction Plectstrin homology domain
Where does PDK1 activation occur? The membrane
What membrane molecule does PKB bind to? Phosphatidynositol-3,4-bisphosphate
Inactive PKB Structure Has a pH domain and an activation lip hiding the kinase
Part of PKB that binds to PIP2 pH domain
PKB binds to PIP2 Causing partial activation
Partial Activation caused by PDK1 phosphorylating its activation lip
Full activation caused by PDK2 phosphorylating its C terminus
PKB moves GLUT4 to membrane (T/F) True
PKB causes Glycogen breakdown (T/F) False- it causes glycogen synthesis
PKB increases protein synthesis (T/F) True
PKB phosphorylates Glycogen Synthase Kinase (T/F) True- this prevents the deactivation of glycogen synthase
PDK1 directly phosphorylates PKB (T/F) True
What allows the different proteins to bind to T.K? The aa surrounding the tyrosine kinase
