Retinoic acid is the form of vitamin A that is involved in the regulation of gene expression. It binds to specific receptors on the cell nucleus, and this complex can then bind to DNA to activate or repress certain genes. Retinol and retinal are involved in vision, while retinol-binding protein is responsible for transporting vitamin A in the blood. Retinolic acid is not a recognized form of vitamin A.
