Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables semaphorin receptor activity. Involved in gonadotrophin-releasing hormone neuronal migration to the hypothalamus and olfactory nerve formation. Acts upstream of or within several processes, including dichotomous subdivision of terminal units involved in salivary gland branching; neuron projection morphogenesis; and semaphorin-plexin signaling pathway. Located in membrane. Is expressed in several structures, including central nervous system; cranial nerve; genitourinary system; lung; and sensory organ. Orthologous to human PLXNA1 (plexin A1).
