Does Increasing Camp Cause Smooth Muscle Relaxation?
Does Increasing Camp Cause Smooth Muscle Relaxation? Unlike cardiac muscle, increased cAMP in smooth muscle causes relaxation. The reason for this is that cAMP normally inhibits myosin light chain kinase, the enzyme that is responsible for phosphorylating smooth muscle myosin and causing contraction. What happens when cAMP increases? Many different cell responses are mediated by
