Answer:
In addition to activating protein kinase C, the phospholipid derived membrane by-product, DAG (Diacylglycerol), activates the RAS pathway that involves a cascade of kinase activation culminating in activation of the AP-1 transcription factor.
Step-by-step explanation:
DAG is known to activate PKC enzymes which are involved in several signal transduction cascades and DAG is also known to activate RAS, a GTP binding protein which in turn stimulates protein kinases involved in various growth factor responses.
