Nrp1 Gene Summary [Rat]
Enables semaphorin receptor activity. Involved in several processes, including negative regulation of axon extension involved in axon guidance; positive regulation of platelet-derived growth factor receptor signaling pathway; and positive regulation of smooth muscle cell migration. Located in cell surface; growth cone; and neuronal cell body. Biomarker of transient cerebral ischemia. Human ortholog(s) of this gene implicated in lung non-small cell carcinoma and tetralogy of Fallot. Orthologous to human NRP1 (neuropilin 1). [provided by Alliance of Genome Resources, Jul 2025]
