Description_x000D_ General description_x000D_ Seladin-1 (selective Alzheimer′s disease indicator-1) is an anti-apoptotic gene. It is a human homolog of the Diminuto/Dwarf1 gene described in plants andC. elegans. Seladin-1 is encoded by the DHCR24 (3-b-hydroxysterol-D-24-reductase) gene, a flavin-adenine-dinucleotide (FAD)-dependent oxidoreductase. It is mainly located in the endoplasmic reticulum._x000D_ Immunogen_x000D_ synthetic peptide corresponding to amino acids 68-85 of human seladin-1, conjugated to KLH._x000D_ Application_x000D_ Anti-Seladin-1 antibody produced in rabbit has been used in immunoblotting._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Seladin-1 (selective Alzheimer′s disease indicator-1) catalyzes the conversion of desmosterol to cholesterol. It prevents apoptosis via inhibition of caspase-3, a key mediator of the apoptotic cascade, suggesting that seladin-1 may be involved in the regulation of cell survival and death. Decreased expression of seladin-1 in specific neurons is linked to Alzheimer′s disease (AD). Seladin-1 functions as a key mediator of Ras-induced senescence in mouse and human fibroblasts. It protects neurons from β-amyloid toxicity and oxidative stress. Seladin-1 is involved in cholesterol homeostasis.
