Anti-retinol binding protein 5, cellular antibodies enable researchers to detect and measure the retinol binding protein 5, cellular antigen in biological samples. This target is a reported synonym of the RBP5 gene, which encodes retinol binding protein 5. This protein is reported to be an intracellular transport of retinol. The human version of retinol binding protein 5, cellular has a canonical amino acid length of 135 residues and a protein mass of 15.9 kilodaltons. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include cellular retinol-binding protein III, putative cellular retinol-binding protein CRBP III, and retinol binding protein 5, cellular.
