Predicted to enable signaling receptor activity. Involved in corpus callosum development and negative regulation of neuron projection development. Predicted to be located in several cellular components, including external side of plasma membrane; membrane raft; and perikaryon. Predicted to be anchored component of plasma membrane. Predicted to be active in cell surface; extracellular matrix; and extracellular space. Is expressed in brain; cranial ganglion; and peripheral nervous system. Orthologous to human RTN4RL2 (reticulon 4 receptor like 2). [provided by Alliance of Genome Resources, Apr 2022]
