Description Erythroid 15-lipoxygenase (15-LOX) synthesized in the early stages of erytropoiesis catalyses the degradation of lipids and is an important factor responsible for the degradation of mitochondria during reticulocyte maturation. The 3'UTR of 15-LOX mRNA contains tandem repeat sequences, referred to as "DICE" for "DIfferentiation Control Element" which specifically bind to regulatory proteins, formerly called LOX-BP. This binding specifically inhibits 15-LOX mRNA translation. In rabbit 15-LOX mRNA, there have been found 10 tandem copies of the repeat sequence, but only 4 (3 tandem) in human. Experimentally, a functional DICE consisting of two repeat elements has been described. The regulatory binding proteins have been identified as hnRNP K and hnRNP E1.
