Retinoid receptors are type II 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.
Subtypes include:
- Retinoic acid receptors (RARs)
- Retinoid X receptors (RXRs)
- RAR-related orphan receptors (RORs)
