Function

Retinol-binding protein that mediates retinol transport in blood plasma. Delivers retinol from the liver stores to the peripheral tissues. Transfers the bound all-trans retinol to STRA6, that then facilitates retinol transport across the cell membrane.

Biological Context

Subcellular Location: Secreted
Tissue Specificity: Detected in blood plasma (at protein level)
