Document Summary
We talked about 3 different ways tat the cell can signal each. Yeast are single eukaryotic cells and have different pathways fig 15-50 is showing g- protein coupled receptors. In yeast they have the blue scaffold proteins that hold together all the singling pathway. Even though they are using similar types of kinases this can help to hold together specific kinases so a activate b and c and so on. So scaffold proteins are key of holding kinases together and preventing cross talk between these two pathways. They have slightly different although similar ways of holding these pathways together. Receptor triose kinases interact specifically with the inside. This is very important in term of timing and specific that these interacting proteins only see the activated receptor. Pdgf receptor is a growth factor that signal the cells to divide and to grow and a lot of cells have it on the cell receptor.
