Predicted to enable identical protein binding activity and semaphorin receptor activity. Predicted to be involved in several processes, including generation of neurons; regulation of GTPase activity; and regulation of cell shape. Predicted to act upstream of or within several processes, including cerebellar granule cell precursor tangential migration; chordate embryonic development; and limb bud formation. Predicted to be part of semaphorin receptor complex. Predicted to be integral component of plasma membrane. Orthologous to human PLXNA2 (plexin A2).
