SSD-containing protein, process for producing the same and use thereof

摘要

The present invention relates to a novel SSD(sterol-sensing domain)-containing protein derived from human liver, human testis and human brain, or a salt thereof, and a DNA encoding the same. Studies on the tissue-specificity of the protein expression, the expression change depending the intracellular cholesterol level, production of the transformant, and the site-specific expression in brain regions of a patient with Alzheimer's disease are disclosed.
