Automated description from the Alliance of Genome Resources (Release 5.3.0)
Enables semaphorin receptor activity. Involved in several processes, including axon guidance; cranial nerve structural organization; and maintenance of synapse structure. Acts upstream of or within several processes, including nervous system development; regulation of axon extension involved in axon guidance; and regulation of negative chemotaxis. Is active in cerebellar climbing fiber to Purkinje cell synapse. Is expressed in several structures, including alimentary system; nervous system; and sensory organ. Orthologous to human PLXNA4 (plexin A4).
