Predicted to enable 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 dichotomous subdivision of terminal units involved in salivary gland branching; neuron projection morphogenesis; and regulation of smooth muscle cell migration. Predicted to be located in cytosol; membrane; and nucleoplasm. Predicted to be part of semaphorin receptor complex. Predicted to be integral component of plasma membrane. Orthologous to human PLXNA1 (plexin A1). [provided by Alliance of Genome Resources, Apr 2022]
