20. These results suggest that the activity of PCFT promoter is basically induced by KLF4 and the gradiented expression profile of PCFT may be at least in part accounted for by those of HNF4alpha, CDX2 and C/EBPalpha. PMID: 23313509
21. The monomeric state of proton-coupled folate transporter is the functional state, substrate translocation does not depend on homo-oligomerization. PMID: 23601781
22. PCFT is abundantly expressed in human tumors and is active at pHs characterizing the tumor microenvironment PMID: 22954694
23. Loss of intrinsic Gly338Cys-PCFT function is due solely to impaired oscillation of the carrier between its conformational states. PMID: 22843796
24. The role of GXXG motif is consistent with a molecular structural model in which this motif and Ile188 are accessible to the PCFT aqueous translocation pathway. PMID: 22785121
25. HCP1 is involved in low-affinity heme-Fe uptake by Caco-2 cells. PMID: 22496243
