### Quiz Question: Understanding DAG in Cell Signaling #### Question: **Which of the following is true of DAG?** #### Options: 1. ○ The DAG pathway allows Ca++/Calmodulin-dependent kinases to phosphorylate other protein targets. 2. ○ DAG is in the cytoplasm and releases Ca2+ from the ER. 3. ○ DAG binds to IP3 receptors. 4. ○ DAG is in the plasma membrane and activates PKC. #### Explanation: In cellular signaling, **Diacylglycerol (DAG)** plays a crucial role. DAG is a lipid-derived second messenger involved in signal transduction pathways. Here’s a brief description to help you understand each option: 1. **The DAG pathway allows Ca++/Calmodulin-dependent kinases to phosphorylate other protein targets.** - This statement is incorrect. DAG is involved in the activation of Protein Kinase C (PKC) rather than Ca++/Calmodulin-dependent kinases. 2. **DAG is in the cytoplasm and releases Ca2+ from the ER.** - This statement is incorrect. DAG is typically localized to the plasma membrane. 3. **DAG binds to IP3 receptors.** - This statement is incorrect. IP3 receptors are located on the endoplasmic reticulum and are specifically activated by Inositol trisphosphate (IP3), not DAG. 4. **DAG is in the plasma membrane and activates PKC.** - This statement is correct. DAG is associated with the plasma membrane where it plays a role in the activation of Protein Kinase C (PKC), which is crucial for various cellular functions. #### Correct Answer: 4. **DAG is in the plasma membrane and activates PKC.**
