RXR (retinoid X receptor)

RXR (retinoid X receptor) is a type of protein found in our cells that helps control gene activity by acting as a switch. It binds to specific molecules called ligands (like retinoids) and partners with other receptors to regulate important processes such as cell growth, development, and immune response. RXR functions as a central hub, forming partnerships with different nuclear receptors to fine-tune gene expression. This regulation is essential for maintaining health and can influence how our body responds to hormones and vitamins.
