======= RBP4 ======= == Gene Information == * **Official Symbol**: RBP4 * **Official Name**: retinol binding protein 4 * **Aliases and Previous Symbols**: N/A * **Entrez ID**: [[https://www.ncbi.nlm.nih.gov/gene/?term=5950|5950]] * **UniProt**: [[https://www.uniprot.org/uniprot/P02753|P02753]] * **Interactions**: [[https://thebiogrid.org/search.php?search=RBP4&organism=9606|BioGRID]] * **PubMed articles**: [[https://www.ncbi.nlm.nih.gov/pubmed/?term=gene%20RBP4|Open PubMed]] * **OMIM**: [[https://omim.org/entry/180250|Open OMIM]] == Function Summary == * **Entrez Summary**: This protein belongs to the lipocalin family and is the specific carrier for retinol (vitamin A alcohol) in the blood. It delivers retinol from the liver stores to the peripheral tissues. In plasma, the RBP-retinol complex interacts with transthyretin which prevents its loss by filtration through the kidney glomeruli. A deficiency of vitamin A blocks secretion of the binding protein posttranslationally and results in defective delivery and supply to the epidermal cells. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: Retinol-binding protein that mediates retinol transport in blood plasma (PubMed:5541771). Delivers retinol from the liver stores to the peripheral tissues (Probable). Transfers the bound all-trans retinol to STRA6, that then facilitates retinol transport across the cell membrane (PubMed:22665496). {ECO:0000269|PubMed:22665496, ECO:0000305,
