Predicted to enable Notch binding activity. Predicted to be involved in central nervous system development. Predicted to act upstream of or within Notch receptor processing; glial cell differentiation; and skeletal muscle fiber development. Predicted to be located in several cellular components, including dendrite; early endosome; and neuronal cell body. Orthologous to human DNER (delta/notch like EGF repeat containing).
