Protein Information
Synonyms TPP1
Function Binds alpha-tocopherol, enhances its transfer between separate membranes, and stimulates its release from liver cells (PubMed:7887897). Binds both phosphatidylinol 3,4-bisphosphate and phosphatidylinol 4,5-bisphosphate; the resulting conformation change is important for the release of the bound alpha-tocopherol (By similarity).
Cellular Location Cytoplasm.

This gene encodes a soluble protein that binds alpha-trocopherol, a form of vitamin E, with high selectivity and affinity. This protein plays an important role in regulating vitamin E levels in the body by transporting vitamin E between membrane vesicles and facilitating the secretion of vitamin E from hepatocytes to circulating lipoproteins. Mutations in this gene cause hereditary vitamin E deficiency (ataxia with vitamin E deficiency, AVED) and retinitis pigmentosa.
