Retinol binding protein 5, cellular
Retinol-binding protein 5
FunctionIntracellular transport of retinol.
Tissue specificityHigher expression in adult kidney and liver and to a lesser extent in adult and fetal spleen, adult lymph nodes and appendix, and fetal liver and kidney. Strongly decreased in hepatocellular carcinoma tissues (at protein level).
Sequence similaritiesBelongs to the calycin superfamily. Fatty-acid binding protein (FABP) family.
DomainForms a beta-barrel structure that accommodates hydrophobic ligands in its interior.
