Retinoid receptor
# Retinoid receptor

Retinoid receptors are nuclear receptors (a class of proteins) that bind to retinoids. When bound to a retinoid, they act as transcription factors, altering the expression of genes with corresponding response elements. Significant age-related declines in the levels of retinoid receptors in the forebrains of rats have been reversed by supplementation with the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which can restore neurogenesis.

Subtypes include:

* Retinoic acid receptors (RARs)
* Retinoid X receptors (RXRs)
* RAR-related orphan receptors (RORs)
