A compound attribute that is the ratio of amount of E3 ubiquitin-protein ligase NRDP1 (human) in blood to amount of NEDD4-like E3 ubiquitin-protein ligase WWP2 (human) in blood. The trait is RNF41/WWP2 protein level ratio in blood (OBA_2053149). Also known as: the ratio of amount of E3 ubiquitin-protein ligase NRDP1 (human) in blood to amount of NEDD4-like E3 ubiquitin-protein ligase WWP2 (human) in blood.
