It is thought to participate in the uptake and/or intracellular metabolism of vitamin A. Vitamin A is a fat-soluble vitamin necessary for growth, reproduction, differentiation of epithelial tissues, and vision. This protein may also modulate the supply of retinoic acid to the nuclei of endometrial cells during the menstrual cycle. [provided by RefSeq, Aug 2015] Annotation information Note: RBP2 (Gene ID: 5948) and KDM5A (Gene ID: 5927) share the RBP2 symbol/alias in common. RBP2 is a widely used alternative name for lysine demethylase 5A (KDM5A), which can be confused with the official symbol for retinol binding protein 2 (RBP2).
