Anti-STRA6 from rabbit

Stimulated by retinoic acid gene 6 protein (UniProt: O70491; also known as Retinoic acid-responsive protein, STRA6) is encoded by the Stra6 gene (Gene ID: 20897) in murine species. STRA6 is a multi-pass membrane protein that acts as a high-affinity cell-surface receptor for the complex retinol-retinol binding protein (RBP/RBP4). It has one intramembrane and nine transmembrane helices in a dimeric assembly. It acts by removing retinol from RBP/RBP4 and transports it across the plasma membrane, where it can be metabolized. This mechanism does not depend on endocytosis. Binds to RBP/RBP4 with high affinity. Increases cellular retinol uptake from the retinol-RBP complex. STRA6 is widely expressed in the embryo and it in adults it is expressed choroid plexus and the brain microvascular cells that form the blood-organ barrier. It is also expressed in the retinal pigment epithelium, seminiferous epithelium in testis, the yolk sac, and in chorioallantoic placenta. Its expression in Sertoli cells depends on the stage of the spermatogenic cycle. STRA6 can be induced by retinoic acid and it is shown to be synergistically up-regulated by Wnt1 and retinoid in mammary epithelial cells. Mutations in Stra6 gene have been linked to the Matthew-Wood syndrome that is characterized by pulmonary agenesis/hypoplasia; microphthalmia/anophthalmia; and congenital cardiac, digestive, and urogenital malformations.
