The inositol sugar head group of phosphatidylinositols (also called inositol phospholipids) are variably phosphorylated to produce PIPs.

One class of cell surface receptors we have discussed in this course are the receptor tyrosine kinases (RTKs). RTKs are single pass transmembrane proteins. a. How are RTKs activated? b. RTK activation leads to phosphorylation of tyrosines on the receptor’s cytosolic tail. What is the function of these phosphorylated tyrosines during cell signaling? (hint: you might mention the protein domain that binds to them)? c. A common outcome of RTK signaling is the activation of Ras; however, Ras is lipid modified and embedded in the membrane. How does Ras send a signal that reaches the nucleus?
