What is the official name of the RARA gene?
The official name of this gene is “retinoic acid receptor, alpha.”
RARA is the gene's official symbol. The RARA gene is also known by other names, listed below.

What is the normal function of the RARA gene?
The RARA gene provides instructions for making a transcription factor called the retinoic acid receptor, alpha (RARα). A transcription factor is a protein that attaches (binds) to specific regions of DNA and helps control the activity of particular genes. The RARα protein controls the activity (transcription) of genes that are important for the maturation (differentiation) of immature white blood cells beyond a particular stage called the promyelocyte.
The RARα protein binds to specific regions of DNA and attracts other proteins that help block (repress) gene transcription, the first step in protein production. In response to a specific signal, the repressive proteins are removed and other proteins that induce gene transcription bind to the RARα protein, allowing gene transcription and cell differentiation.
Does the RARA gene share characteristics with other genes?
The RARA 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.
