What is the official name of the NR4A2 gene?

The official name of this gene is “nuclear receptor subfamily 4, group A, member 2.”

NR4A2 is the gene's official symbol. The NR4A2 gene is also known by other names, listed below.

What is the normal function of the NR4A2 gene?

The NR4A2 gene provides instructions for making a protein found in the brain and the adrenal gland (the hormone-producing gland located on top of each kidney). In the brain, the NR4A2 protein plays a key role in prompting certain nerve cells to specialize (differentiate) and produce a chemical messenger called dopamine. Dopamine transmits messages that help the brain control physical movement and emotional behavior.

Does the NR4A2 gene share characteristics with other genes?

The NR4A2 gene belongs to a family of genes called NR (nuclear hormone receptors).

A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? ( in the Handbook.

Where is the NR4A2 gene located?

Cytogenetic Location: 2q22-q23

Molecular Location on chromosome 2: base pairs 156,324,431 to 156,332,774

The NR4A2 gene is located on the long (q) arm of chromosome 2 between positions 22 and 23.

The NR4A2 gene is located on the long (q) arm of chromosome 2 between positions 22 and 23.

More precisely, the NR4A2 gene is located from base pair 156,324,431 to base pair 156,332,774 on chromosome 2.
