Following statements are regarding to the phosphoinositide signaling pathway.
A. Many RTKs and cytokine receptors can initiate the IP3/ DAG signaling pathway by activating phospholipase Cβ (PLCβ), a different PLC isoform.
B. Activated RTKs and cytokine receptors also can initiate another phosphoinositide pathway by binding a PI-3 kinase, thereby allowing the enzyme access to its membrane-bound phosphoinositide substrates, which then become phosphorylated at the 3 position.
C. Protein kinase B (PKB) becomes partially activated by binding to PI 3-phosphates with its PH domain.
D. Full activation of PKB requires phosphorylation by the kinase PDK1, which is also recruited to the membrane by binding to PI 3-kinase, and by a second kinase, PDK2.
