Gene Gene information from NCBI Gene database.
Entrez ID 7274
Gene name Alpha tocopherol transfer protein
Gene symbol TTPA
Synonyms (NCBI Gene)
ATTPAVEDTTP1alphaTTP
Chromosome 8
Chromosome location 8q12.3
Summary 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
