3. Explain how activation of diacylglycerol (DAG) kinase (converts DAG to phosphatidic acid) would affect signaling in the phosphoinositide pathway
Homework Answers
3ANS)
--> Diacylglycerol with the assistance of calcium particles is in charge of initiation of protein kinase C in the phosphoinositide pathway. At the point when diacylglycerol kinase gets enacted, it will change over diacylglycerol to phosphatidic corrosive. Consequently, there will no diacylglycerol to actuate protein kinase C. This is the reason the initiation of diacylglycerol kinase would restrain motioning by the phosphoinositide pathway.

A complex signaling pathway in yeast allows the cells to accumulate high concentrations of glycerol if they are exposed to high extracellular concentration of salt or glucose. The increased osmolarity of the extracellular medium activates Ras, which in turn activates adenylate cyclase. A second pathway, the HOG (high osmolarity glycerol) pathway activates the MAP kinase pathway. The target protein is the enzyme PFK2, which is activated by phosphorylation. (PFK2 produces an allosteric regulator that activates glycolysis, which ultimately produces glycerol.)...

Drosopholia eye development is an example of cell differentiation directed by signal binding to a receptor tyrosine kinase (RTK). In this pathway, R7 photoreceptor development requires a receptor (SEV, sevenless), which is activated by binding to a plasma membrane bound signal (BOSS, bride-of-sevenless) displayed on the adjacent R8 cell Receptor activation leads to activation of RAS via two proteins, Drk (down- stream of receptor kinases) and Sos (son-of-sevenless). Activated RAS leads to activation of a phosphorylation cascade that activates the...
