General annotation (Comments)

Function	Catalyzes the reduction of 3-ketodihydrosphingosine (KDS) to dihydrosphingosine (DHS).
Catalytic activity	Sphinganine + NADP+ = 3-dehydrosphinganine + NADPH. Ref.6
Pathway	Lipid metabolism; sphingolipid metabolism.
Subcellular location	Endoplasmic reticulum membrane; Multi-pass membrane protein Ref.6.
Tissue specificity	Expressed in all tissues examined. Highest expression in placenta. High expression in lung, kidney, stomach and small intestine, low expression in heart, spleen and skeletal muscle. Weakly expressed in normal hematopoietic tissues. Higher expression in some T-cell malignancies and PHA-stimulated lymphocytes.
Involvement in disease	Note=A chromosomal aberration involving KDSR is a cause of follicular lymphoma; also known as type II chronic lymphatic leukemia. Translocation t(2;18)(p11;q21) with a Ig J kappa chain region.
Sequence similarities	Belongs to the short-chain dehydrogenases/reductases (SDR) family.
