Predicted to enable identical protein binding activity and transmembrane receptor protein tyrosine kinase activity. Involved in energy homeostasis; negative regulation of lipid catabolic process; and positive regulation of dendrite development. Acts upstream of or within several processes, including hippocampus development; response to environmental enrichment; and swimming behavior. Predicted to be located in axon; cell body; and plasma membrane. Predicted to be part of receptor complex. Predicted to be integral component of plasma membrane. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Orthologous to human ALK (ALK receptor tyrosine kinase).
