G-Protein Coupled Receptors — Flashcards

In the adenylyl cyclase mechanism of cellular signaling, the second messenger _____ activates protein kinase A, which then phosphorylates specific proteins to produce physiologic actions

Gi proteins _____ the cAMP signaling cascade

_____ receptors bind glycoproteins and contain three domains; an extracellular domain for ligand binding, a transmembrane domain, and an intracellular domain coupled with heterotrimeric G proteins

Inhibition of Gi via the pertussis toxin results in _____ levels of cAMP

Binding of atrial natriuretic peptide to its receptor guanylyl cyclase causes conversion of _____ to cGMP

In the phospholipase C mechanism of cellular signaling, _____ and diacylglycerol (DAG) activate protein kinase C, which phosphorylates specific proteins to produce physiologic actions

Gq proteins _____ the IP3-DAG signaling cascade

In the phospholipase C mechanism of cellular signaling, the _____ complex activates phospholipase C, which then catalyzes the liberation of DAG and IP3 from PIP2

The events that occur during the activation of GPCR are as follows: No answer _____

Cyclin _____ and Cyclin A-CDK1 are active in S phase
