Determining the structure of nuclear receptor has implications for a host of diseases

In a study published this week in PLoS Biology, Eric Xu and colleagues have determined the molecular structure of a nuclear receptor, which regulates the expression of specific genes within cells, that may serve as a drug target for diseases related to heart and blood vessel development, human embryonic development and female infertility. Researchers also found that the receptor, named COUP-TFII, is activated by retinoic acid, a form of Vitamin A.
