Enables sodium channel inhibitor activity and ubiquitin protein ligase activity. Acts upstream of or within several processes, including negative regulation of systemic arterial blood pressure; regulation of bicellular tight junction assembly; and regulation of ion transport. Predicted to be located in Golgi apparatus and endosome. Predicted to be active in cytoplasm. Predicted to colocalize with plasma membrane. Is expressed in several structures, including central nervous system; genitourinary system; gut; limb segment; and retina. Human ortholog(s) of this gene implicated in periventricular nodular heterotopia. Orthologous to human NEDD4L (NEDD4 like E3 ubiquitin protein ligase).
