Nur (biology)
Encyclopedia
Nur is a family of orphan
nuclear receptors which act as transcription factors in neuron development and maintenance. Recently, members of the NR4A family have been implicated in the control of skeletal muscle metabolism.
Three members have been identified in humans:
Orphan
An orphan is a child permanently bereaved of or abandoned by his or her parents. In common usage, only a child who has lost both parents is called an orphan...
