26884338 A homology model of PCFT, based upon the Escherichia coliglycerol 3-phosphate transporter structure, predicted that PCFT transmembrane domains (TMDs) 1, 2, 7, and 11 form an extracellular gate in the inward-open conformation.
26193446 We conclude that SLC46A1/PCFT and SLC19A1/RFC-1 are associated with DFS of patients with colorectal cancer and hypothesize that poor response to 5-fluorouracil plus leucovorin therapy in some patients may be linked to low expression of these genes.
25877470 results imply that TMDs 3 and 6 provide critical interfaces for formation of hPCFT oligomers, which might be facilitated by the GXXXG motifs in TMD2 and TMD4.
25801697 Report sustained inhibition of PCFT by myricetin.
25697897 this is the first study to simultaneously evaluate both DNA methylation and protein expression of all three folate transporter genes, FOLR1, PCFT, and RFC1, in colorectal cancer.
25608532 The current study addresses the role of Tyr residues in SLC46A1 function; and identifies four residues that enhance the affinity of the carrier for its substrates and decrease the rate at which the carrier oscillates between its conformational states.
25124723 SLC46A1 genotype may help to identify patients with increased risk of methotrexate-related toxicity.
25053408 Data indicate that 28/33 cysteine-less proton-coupled folate transporter (PCFT) mutant HeLa cells were active for [(3)H]methotrexate uptake.
24597986 the RFC1 G80A polymorphism does not seem to be a good marker of MTX-related toxicity in pediatric ALL.
24396145 The molecular bases for methotrexate resistance associated with loss of SLC19A1 transport and for hereditary folate malabsorption, attributable to mutant SLC46A1, were determned (review).
