Enables argininosuccinate lyase activity. Involved in several processes, including cellular response to cytokine stimulus; cellular response to organic cyclic compound; and response to peptide hormone. Located in several cellular components, including cell body fiber; mitochondrial outer membrane; and perikaryon. Human ortholog(s) of this gene implicated in amino acid metabolic disorder and argininosuccinic aciduria. Orthologous to human ASL (argininosuccinate lyase).
