We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.
Retinol-binding protein
From Proteopedia
Retinol-binding protein (RBP) are carrier proteins which bind retinol (vitamin A alcohol). Human RBP4 is the carrier of retinol in the blood. It delivers retinol from the liver to the peripheral tissues. RBP also functions in regulation, metabolism and activities of retinoids. Retinol is being protected from oxidation and becomes soluble when bound to RBP. RBP is used to assess vitamin A deficiency as it binds 1:1 to retinol. RBP is classified according to its site of activity. Plasma RBP (PRBP) carries retinol in blood while cellular RBP (CRBP) carries retinol in the cell.
