Anti-RBP / Retinol Binding Protein 1, clone rRBP1/872

1 mg/ml in 1X PBS, BSA free, sodium azide free. Retinol Binding Protein 1 or Cellular Retinol Binding Protein 1 (CRBP 1), a single-chain glycoprotein belonging to the superfamily of hydrophobic molecule transporter proteins, which is responsible for transport of retinol (vitamin A1) from the liver to peripheral target tissues, like the eye, where it mediates the cellular uptake. RBP1 is synthesized by hepatic parenchymal cells where it becomes bound to its ligand retinol and is then released into the circulation, where it binds further to the protein transthyretin, to form a transporting complex, which is big enough not to be lost by filtration through the kidney glomeruli. It is detected in nearly all tissues with higher expression in adult ovary, pancreas, pituitary gland, adrenal gland, and fetal liver. Protein function: Cytoplasmic retinol-binding protein (PubMed:22665496, PubMed:26900151, PubMed:28057518). Accepts retinol from the transport protein STRA6, and thereby contributes to retinol uptake, storage and retinoid homeostasis (PubMed:15632377, PubMed:22665496). [The UniProt Consortium]
