A compound attribute that is the ratio of amount of dual adapter for phosphotyrosine and 3-phosphotyrosine and 3-phosphoinositide (human) in blood to amount of Golgi-associated PDZ and coiled-coil motif-containing protein (human) in blood. The trait is DAPP1/GOPC protein level ratio in blood (Ontology of Biological Attributes identifier OBA_2055061). Also known as: the ratio of amount of dual adapter for phosphotyrosine and 3-phosphotyrosine and 3-phosphoinositide (human) in blood to amount of Golgi-associated PDZ and coiled-coil motif-containing protein (human) in blood.
