Nitric oxide accomplishes this by elevating cGMP levels.
NO is a distinctive message. It is a gas, although it does dissolve in an aqueous solution.
It is a free radical with an unshared electron, which will react with thiol groups on proteins to form new complexes.
Unlike other second messengers, NO doesn't need energy to move inside and outside of cells. It can go where it wants, but it does not travel far because it is a reactive free radical.
NO acts within the cell that produces it as a second messenger. It operates as a paracrine molecule able to travel 10–20 cell diameters to affect the biology in surrounding cells. It can form complexes with proteins like hemoglobin, glutathione, and other proteins and then separate from those complexes.
