About This Section

Entrez Gene summary for TTPA Gene:

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. (provided by RefSeq, Nov 2009)

GeneCards Summary for TTPA Gene:

TTPA (tocopherol (alpha) transfer protein) is a protein-coding gene. Diseases associated with TTPA include ataxia with vitamin e deficiency, and spinocerebellar degeneration. GO annotations related to this gene include phosphatidylinositol-3,4-bisphosphate binding and transporter activity. An important paralog of this gene is TTPAL.

UniProtKB/Swiss-Prot: TTPA_HUMAN, P49638

Function: Binds alpha-tocopherol, enhances its transfer between separate membranes, and stimulates its release

from liver cells. 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)
