Enzymes

Enzyme Details
1. Delta(24)-sterol reductase
General function:
Energy production and conversion
Specific function:
Catalyzes the reduction of the delta-24 double bond of sterol intermediates. Protects cells from oxidative stress by reducing caspase 3 activity during apoptosis induced by oxidative stress. Also protects against amyloid-beta peptide-induced apoptosis.
Gene Name:
DHCR24
Uniprot ID:
Q15392
Molecular weight:
60100.805
