So it basically removes the phosphoro group via a process of hydrolysis off of a specific type of amino acid on our protein. And this specific type of protein phosphatase plays a role in regulating the growth of our cells. So it basically plays an important role in controlling cancer. So basically, let's review what each type of our regulation method is. So earlier we spoke about allosteric regulation and this basically involves the binding of some type of specific molecule onto the allosteric site of the enzyme to either activate it or deactivate it. So we actually look at an allosteric regulation in this case.
