  • multi-pass membrane protein
  • basic FUNCTION
  • involved in the cholesterol biosynthetic pathway (first step)
  • enzyme that determines the switch toward sterol biosynthesis
  • in prostate cancer cells its expression is enhanced by androgens, channeling intermediates of the mevalonate/isoprenoid pathway toward cholesterol synthesis
  • plays an important role in the cholesterol biosynthesis pathway as it is responsible for the flow of metabolites into either the sterol or the non-sterol branches of the pathway
  • may be involved in the etiology of hypercholesterolemia
  • key enzyme for endogenous cholesterol production, in the neural stem and progenitor cells of the ventricular zone (VZ)
  • plays a role in barrier permeability and integrity
  • may play an important role in prostate cancer development and its aggressive phenotypes
  • divalent metal-ion-dependent enzyme that catalyzes the two-step reductive `head-to-head' condensatio

    ANIMAL & CELL MODELS
  • mutant murine embryos exhibited a reduced brain size due to the atrophy of the neuronal layers, and died at birth
  • Fdft1-null mice demonstrate embryonic lethality at day 12.5 in conjunction with growth restriction and neurodevelopmental disorders
