23599266 The crystal structure of the alpha-TTP-phosphatidylinositol phosphates (PIPs) complex revealed that the familial vitamin E deficiency-related arginine residues interacted with phosphate groups of the PIPs and that the PIPs binding caused the lid of the alpha-tocopherol-binding pocket to open.
23079030 Single-nucleotide polymorphisms that are commonly found in healthy humans dramatically affect promoter activity of the TTPA gene.
22752767 study demonstrated that alpha -TTP can be upregulated in case of oxidative stress in BeWo trophoblast cells; speculate that possibly, alpha -TTP is notonly involved in normal pregnancy, but also in cases of pregnancy disorders with intense oxidative stress
21110980 Substitution of residues in helices A8 (F165A and F169A) and A10 (I202A, V206A and M209A) decreased the rate of intermembrane ligand transfer as well as protein adsorption to phospholipid bilayers.
20826775 Data show that reduction ("knockdown") of tocopherol transfer protein (TTP) expression resulted in resistance to the vitamin E.
20801516 Observational study of genetic testing. (HuGE Navigator)
19458973 Hydrophobic features of alpha-TTP dominating the binding energy between protein and membrane.
19190344 Genetic variation in TTPA and SEC14L2 is associated with serum alpha-tocopherol but does not have a direct effect on prostate cancer when vitamin E is administered.
19190344 Observational study of gene-disease association and gene-environment interaction. (HuGE Navigator)
19102053 Total deletion of the TTPA gene is expected to be associated with severe phenotype in AVED patients.
