Retinol-binding protein (RBP)

Target
RBP
Molecular classification
Transporter, Lipocalin
01

Overview

Retinol-binding protein (RBP) is a lipocalin that mediates the transport of retinol from liver stores to peripheral tissues. It plays a crucial role in vitamin A metabolism and is essential for various biological processes, including vision and cell growth. The protein structure encapsulates retinol, allowing safe delivery within an aqueous environment. While RBP is not typically considered a therapeutic target, it is important for nutritional health and serves as a biomarker for visceral protein mass.
