Then we have the Pip three dependent protein kinase which is used to basically activate protein kinase B, also known as AKT. And what protein kinase B does is it basically stimulates the movement of glucose transporters into the membrane of our cells, for instance, skeletal muscle cells. And then these skeleton muscle cells can essentially uptake the glucose molecules and transform the glucose molecules into Glycogen as a result of the activity of these protein kinases. Now, in the EGF signaling pathway we discussed four different types of protein kinases. So just like in the case of insulin here, the EGF receptor also contains a tyrosine protein kinase that is needed to actually initiate that signaling pathway. And then we also examined three other examples of kinases.
