CC -!- FUNCTION: Cytoplasmic retinol-binding protein (PubMed:7744071). Accepts
CC retinol from the transport protein STRA6, and thereby contributes to
CC retinol uptake, storage and retinoid homeostasis.
CC {ECO:0000250|UniProtKB:P09455, ECO:0000269|PubMed:7744071}.
CC -!- SUBUNIT: Interacts (only as retinol-free apoprotein) with STRA6.
CC {ECO:0000250|UniProtKB:P09455}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q00915}. Lipid
CC droplet {ECO:0000250|UniProtKB:Q00915}.
CC -!- DOMAIN: Forms a beta-barrel structure that accommodates hydrophobic
CC ligands in its interior. {ECO:0000250|UniProtKB:P09455}.
CC -!- SIMILARITY: Belongs to the calycin superfamily. Fatty-acid binding
CC protein (FABP) family. {ECO:0000305}.
