3-dehydrosphinganine reductase

3-dehydrosphinganine reductase also known as 3-ketodihydrosphingosine reductase (KDSR) or follicular variant translocation protein 1 (FVT1) is an enzyme that in humans is encoded by the KDSR gene.

Function
3-dehydrosphinganine reductase catalyzes the chemical reaction: The two substrates of this enzyme are sphinganine and oxidised nicotinamide adenine dinucleotide phosphate (NADP+). Its products are 3-ketosphinganine, reduced NADPH, and a proton. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. This enzyme participates in sphingolipid metabolism. == Tissue distribution ==
Tissue distribution
Follicular lymphoma variant translocation 1 is a secreted protein which is weakly expressed in hematopoietic tissue. == Clinical significance ==
Clinical significance
FVT1 shows a high rate of transcription in some T cell malignancies and in phytohemagglutinin-stimulated lymphocytes. The proximity of FVT1 to BCL2 suggests that it may participate in the tumoral process. == References ==
