One of the retinoic acid-inducible cDNA clones in mouse embryonal carcinoma F9 cells encodes a novel isoenzyme of fructose 1,6-bisphosphatase.
Rae-30, one of the retinoic acid (RA)-inducible cDNA clones in mouse embryonal carcinoma F9 cells, was sequenced and the deduced RAE-30 protein showed about a 70% homology to mammalian fructose 1,6-bisphosphatase (EC 3.1.3.11) (FBPase), in comparison to over 85% homology observed among the previously documented rat liver, pig kidney and human leukemic HL-60 cell FBPases. The Rae-30 mRNAs were not detected in various tissues of adult mice, including the liver and kidney, but were detected in a placenta and predominantly in the intestine of adult mice. These findings indicate that the Rae-30 cDNA encodes a novel isoenzyme of FBPase, which is likely to be involved in early differentiation in mammalian cells.
