WebPhospholipase c cleaves which membrane-bound molecule? A) PIP2 b) PIP3 c IP3 d) protein 6. In the phosphoinositide cascade, a calcium channel is activated by: a) the heterotrimeric G protein b) cyclic AMP c) IP3 d) DAG 7. In the cascade, protein kinase c is activated by Ca+2 and protein b) cyclic AMPc) IP3 d) DAG a) the heterotrimeric G 8. WebThe phospholipase cleaves PIP 2 , creating DAG and IP 3 . The DAG is sent towards other pathways as a second messenger. The IP 3 is diffused into the ER and binds to the IP 3 gated calcium channel, which allows the gates to open; and out goes Ca 2+ . The Ca 2+ ions flow out of the ER, acting as a second messenger.
