The Concept of Folic Acid in Health and Disease

open access: yesMolecules, 2021
Folates have a pterine core structure and high metabolic activity due to their ability to accept electrons and react with O-, S-, N-, C-bounds.

Identification of Transport-critical Residues in a Folate Transporter from the Folate-Biopterin Transporter (FBT) Family [PDF]

open access: yesJournal of Biological Chemistry, 2010
The Synechocystis Slr0642 protein and its plastidial Arabidopsis (Arabidopsis thaliana) ortholog At2g32040 belong to the folate-biopterin transporter (FBT) family within the major facilitator superfamily. Both proteins transport folates when expressed in Escherichia coli.

Molecular mechanism of substrate recognition by folate transporter SLC19A1

open access: yesCell Discovery, 2022
Folate (vitamin B9) is the coenzyme involved in one-carbon transfer biochemical reactions essential for cell survival and proliferation, with its inadequacy causing developmental defects or severe diseases. Notably, mammalian cells lack the ability to de

In vitro reconstitution of dynamically interacting integral membrane subunits of energy-coupling factor transporters

open access: yeseLife, 2020
Energy-coupling factor (ECF) transporters mediate import of micronutrients in prokaryotes. They consist of an integral membrane S-component (that binds substrate) and ECF module (that powers transport by ATP hydrolysis).

Folate receptor alpha is more than just a folate transporter [PDF]

open access: yesNeurogenesis, 2017
Until recently folate receptor alpha (FRα) has only been considered as a folate transporter. However, a novel role of FRα as a transcription factor was reported by our lab. More recently our lab showed a novel pleiotropic role of FRα: (a) direct transcriptional activation of Oct4, Sox2, and Klf4 genes; and (b) repression of biogenesis of miRNAs that ...

Selenofolate inhibits the proliferation of IGROV1 cancer cells independently from folate receptor alpha

open access: yesHeliyon, 2021
Cancer is one of the main causes of human mortality worldwide and novel chemotherapeutics are required due to the limitations of conventional cancer therapies.

Folate transporter dynamics and therapy with classic and tumor-targeted antifolates

open access: yesScientific Reports, 2021
There are three major folate uptake systems in human tissues and tumors, including the reduced folate carrier (RFC), folate receptors (FRs) and proton-coupled folate transporter (PCFT). We studied the functional interrelationships among these systems for

The mechanism of folate transport in rabbit reticulocytes [PDF]

open access: yesJournal of Clinical Investigation, 1972
Folate transport in phenylhydrazine-induced rabbit reticulocytes was studied with the non-metabolized folate-analog, methotrexate. The time-course of methotrexate uptake into a mixed population of reticulocytes and mature erythrocytes is a two-component process consisting of a small, but rapid, initial uptake phase followed by a much slower uptake ...

Protective effects of pyrroloquinoline quinone in brain folate deficiency

open access: yesFluids and Barriers of the CNS, 2023
Background Folates (Vitamin B9) are critical for normal neurodevelopment and function, with transport mediated by three major pathways: folate receptor alpha (FRα), proton-coupled folate transporter (PCFT), and reduced folate carrier (RFC).

Folate catabolites in spot urine as non-invasive biomarkers of folate status during habitual intake and folic acid supplementation. [PDF]

open access: yes, 2013
Folate status, as reflected by red blood cell (RCF) and plasma folates (PF), is related to health and disease risk. Folate degradation products para-aminobenzoylglutamate (pABG) and para-acetamidobenzoylglutamate (apABG) in 24 hour urine have recently ...
