Neurotrophin-4 (NT-4),[5] also known as neurotrophin-5 (NT-5), is a protein that in humans is encoded by the NTF4gene.[6] It is a neurotrophic factor that signals predominantly through the TrkBreceptor tyrosine kinase.[7][8] NT-4 was first discovered and isolated from xenopus and viper in the year 1991 by Finn Hallbook et.al[9]
