Nur (nuclear receptor subfamily 4) is a family of orphan nuclear receptors which act as transcription factors in neuron development and maintenance. Three members have been identified in humans:
- nerve Growth factor IB (Nur77, or NR4A1),
- nuclear receptor related 1 protein (Nurr1, or NR4A2), and
- neuron-derived orphan receptor 1 (Nor-1, or NR4A3).
