Function
Multicopper oxidase that may be involved in copper homeostasis and oxidative stress response, and that is necessary for root growth inhibition by low phosphate conditions. Functions together with LPR2 and PDR2 in a common pathway that adjusts root meristem activity to phosphate availability. Oxidizes the substrate 2,2'-azinobis-(3-ethylbenzthiazoline-6-sulphonate) in vitro.
