Prostaglandin E synthase 3 (cytosolic) is a Prostaglandin E synthase enzyme that in humans is encoded by the PTGES3 gene.[5]

The protein encoded by this gene is also known as p23 which functions as a chaperone which is required for proper functioning of the glucocorticoid and other steroid receptors.[6]
