Plxna1 Gene Summary [Rat]
Predicted to enable semaphorin receptor activity. Predicted to be involved in several processes, including T cell activation via T cell receptor contact with antigen bound to MHC molecule on antigen presenting cell; nervous system development; and semaphorin-plexin signaling pathway. Predicted to act upstream of or within dichotomous subdivision of terminal units involved in salivary gland branching; neuron projection extension; 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 active in glutamatergic synapse and plasma membrane. Orthologous to human PLXNA1 (plexin A1). [provided by Alliance of Genome Resources, Jul 2025]
