Enables translation factor activity, non-nucleic acid binding and ubiquitin protein ligase activity. Involved in several processes, including positive regulation of cellular component organization; positive regulation of long-term neuronal synaptic plasticity; and protein monoubiquitination. Acts upstream of or within lactation; positive regulation of epidermal growth factor-activated receptor activity; and sperm axoneme assembly. Located in several cellular components, including dendrite; perikaryon; and postsynaptic density. Is expressed in several structures, including limb; limb bud; nervous system; sensory organ; and skin. Orthologous to human NEURL1 (neuralized E3 ubiquitin protein ligase 1).
