A Functional Binding Domain in the Rbpr2 Receptor Is Required for Vitamin A Transport, Ocular Retinoid Homeostasis, and Photoreceptor Cell Survival in Zebrafish

open access: yesCells, 2020
Dietary vitamin A/all-trans retinol/ROL plays a critical role in human vision. ROL circulates bound to the plasma retinol-binding protein (RBP4) as RBP4-ROL. In the eye, the STRA6 membrane receptor binds to circulatory RBP4 and internalizes ROL. STRA6 is,

Evidence for an Essential Role of Megalin in Transepithelial Transport of Retinol [PDF]

open access: yesJournal of the American Society of Nephrology, 1999
Abstract. Transepithelial transport of retinol is linked to retinol-binding protein (RBP), which is taken up and also synthesized in a number of epithelia. By immunocytochemistry of human, rat, and mouse renal proximal tubules, a strong staining in apical endocytic vacuoles, lysosomes, endoplasmic reticulum ...

A multicompartmental model of vitamin A kinetics in rats with marginal liver vitamin A stores.

open access: yesJournal of Lipid Research, 1985
A linear, first-order, constant-coefficient multicompartmental model is presented which describes the dynamics of [3H]retinol turnover in adult rats with normal plasma retinol concentrations but low liver stores (less than 100 micrograms of retinol ...

Retinol Esterification Activity Contributes to Retinol Transport in Stellate Cells.

open access: yesCell Structure and Function, 1999
The mechanisms of retinol transport and accumulation in hepatic stellate cells (HSC) remain to be elucidated. Our previous studies suggested that retinol esterification activity, particularly lecithin:retinol acyltransferase (LRAT) activity, in liver retinoid metabolism is important to elucidate the relationship between retinol uptake by HSC and the ...

Confocal Raman imaging reveals the impact of retinoids on human breast cancer via monitoring the redox status of cytochrome c

open access: yesScientific Reports, 2023
This paper expands the current state of knowledge on impact of retinoids on redox status of cytochrome c in cancers. Little is known how the expression of cytochromes may influence the development of cancers.

Retinol and Retinol-Binding Protein Stabilize Transthyretin via Formation of Retinol Transport Complex

open access: yesACS Chemical Biology, 2010
Transthyretin (TTR) is a plasma hormone carrier protein associated with hereditary and senile forms of systemic amyloid disease, wherein slow tetramer disassembly is thought to be an obligatory step. Plasma transport of retinol is carried out exclusively by the retinol-binding protein (RBP), through complexation with transthyretin.

Serum and intracellular retinol transport in the equine [PDF]

open access: yesBritish Journal of Nutrition, 1982
1. Serum and intracellular distribution of retinol was determined in equines maintained on four levels of vitamin A intake.2. The form of retinol transported in serum was determined by gel filtration and chromatography to be a complex of retinol bound to a protein of molecular weight (MW) of approximately 20000, which was in turn complexed probably ...

Vitamin A transport in plasma of the non-mammalian vertebrates: isolation and partial characterization of piscine retinol-binding protein1

open access: yesJournal of Lipid Research, 1977
Studies were conducted to explore vitamin A transport in the non-mammalian vertebrates, especially Pisces, Amphibia, and Reptilia, and to isolate and partially characterize piscine retinol-binding protein.

Retinoid-binding proteins: similar protein architectures bind similar ligands via completely different ways. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Retinoids are a class of compounds that are chemically related to vitamin A, which is an essential nutrient that plays a key role in vision, cell growth and differentiation. In vivo, retinoids must bind with specific proteins to perform their

Characterization of two post-translationally processed forms of human serum retinol-binding protein: altered ratios in chronic renal failure.

open access: yesJournal of Lipid Research, 1995
Retinol-binding protein (RBP) is the specific blood carrier for the transport of retinol (vitamin A) to target tissues. As the kidney is involved in RBP metabolism, the analysis of RBP species in the serum of patients with chronic renal failure (CRF) was
