Detected in cerebellum, kidney, heart, lung, skeletal muscle and spleen. Strongly expressed in embryos from 9.5 dpc to 10.5 dpc. Expression is much lower at 11.5 dpc and virtually extinct at 15.5 dpc. Detected in neural tube and lateral mesoderm at 9.5 dpc. At 10.5 dpc detected in fore and hind limb buds and lateral plate mesoderm, throughout the neural tube, in mesencephalon and dorsal diencephalon. Belongs to the immunoglobulin superfamily. DCC family.
