Human RXR DBD

RXRα is a member of the nuclear receptor superfamily that mediates signaling by 9-cis retinoic acid, a vitamin A (retinol) derivative. Along with other members of the RXR family, RXRα plays roles in a variety of processes including embryonic patterning and organogenesis, cell proliferation and differentiation. RXRs commonly function as heterodimers with other members of the nuclear receptor superfamily. RXR-α is expressed in mulitple organs in many major physiological systems (central nervous system (CNS), endocrine, metabolic, gastrointestinal, reproductive and cardiopulmonary), with particularly high levels in the liver, preputial gland, skeletal muscle and skin. RXR-α variants have been associated with psychiatric (schizophrenia, autism, alcoholism, bipolar disorder and attention deficit hyperactivity disorder (ADHD)) and immune (psoriasis) disorders.
