Nuclear Receptor Subfamily 4, Group A, Member 1

**Definition:** An orphan nuclear receptor that is closely related to members of the thyroid-steroid receptor gene family. It was originally identified in NERVE CELLS and may play a role in mediation of NERVE GROWTH FACTOR-induced CELL DIFFERENTIATION. However, several other functions have been attributed to this protein including the positive and negative regulation of APOPTOSIS.
