Isolation and Properties of a Human Retinol-transporting Protein
A human retinol-transporting protein has been isolated from the urine of patients with tubular proteinuria. The protein separated into four fractions in the last two purification steps (sulfoethyl Sephadex chromatography and DEAE-Sephadex chromatography). The yield of purified retinol-binding protein (RBP) was 33 to 41% of the amount in concentrates of

Ligand-dependent secretion of rat retinol-binding protein expressed in HeLa cells
A minigene encoding rat retinol-binding protein (RBP) was transfected into HeLa cells, which do not express endogenous RBP, transthyretin, or cellular retinol-binding protein.

Exome analysis identified a novel mutation in the RBP4 gene in a consanguineous pedigree with retinal dystrophy and developmental abnormalities. [PDF]
Retinitis Pigmentosa (RP) is a common form of retinal degeneration characterized by photoreceptor degeneration and retinal pigment epithelium (RPE) atrophy causing loss of visual field and acuities.

Vitamin A equivalency of ß-carotene in healthy adults: limitation of the extrinsic dual-isotope dilution technique to measure matrix effect [PDF]
Data on the vitamin A equivalency of ß-carotene in food are inconsistent. We quantified the vitamin A equivalency (¿g) of ß-carotene in two diets using the dual-isotope dilution technique and the oral¿faecal balance technique.

Real-time Analyses of Retinol Transport by the Membrane Receptor of Plasma Retinol Binding Protein
Vitamin A is essential for vision and the growth/differentiation of almost all human organs. Plasma retinol binding protein (RBP) is the principle and specific carrier of vitamin A in the blood. Here we describe an optimized technique to produce and purify holo-RBP and two real-time monitoring techniques to study the transport of vitamin A by the high ...

Expression Profiles of Cellular Retinol-binding Protein, Type II (CRBP II) in Erlang Mountainous Chickens [PDF]
Cellular retinol-binding protein II (CRBP II) belongs to the family of cellular retinol-binding proteins and plays a major role in absorption, transport, and metabolism of vitamin A.

A Narrative Review of the Role of Transthyretin in Health and Disease
Transthyretin (TTR) is a tetrameric transport protein highly conserved through vertebrate evolution and synthesized in the liver, choroid plexus, and retinal pigment epithelium. TTR transports the thyroid hormone thyroxine and the retinol-binding protein
