neurotrophin TRK receptor activity, neurotrophin TRKA receptor activity, neurotrophin TRKB receptor activity, neurotrophin TRKC receptor activity

Note that mammalian NT-5 was initially named differently from amphibian NT-4 because of sequence differences, but the two genes were later shown to be functionally equivalent [SF:919858].
