Abstract:
We have reported the occurrence of eight splice variants of rat brain fructose 6-phosphate 2-kinase/fructose 2,6-bisphosphatase (RB2K). In the present study, we quantified these splice variants in various tissues using a RNAse protection assay and found a tissue-specific pattern of alternative splicing of the RB2K gene. Splice variants containing exon F were specifically expressed in brain. Moreover, exons D and E were spliced in brain, skeletal muscle and heart. Consequently, eight, six, four and two splice variants were expressed in brain, skeletal muscle, heart and liver plus testis, respectively. These results suggest that distinct RB2K isoforms could be involved in regulation of glycolysis in a tissue-specific manner.

Alternative RNA Splicing
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...
Membrane Asymmetry Regulating Transporters
Flippase
Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...
