Gene Gene information from NCBI Gene database.
Entrez ID 6770
Gene name Steroidogenic acute regulatory protein
Gene symbol STAR
Synonyms (NCBI Gene)
STARD1
Chromosome 8
Chromosome location 8p11.23
Summary The protein encoded by this gene plays a key role in the acute regulation of steroid hormone synthesis by enhancing the conversion of cholesterol into pregnenolone. This protein permits the cleavage of cholesterol into pregnenolone by mediating the transp
