Brain Tumor Drug in Frogs A New Report

...lls by latching on to the molecule and cutting it into smaller sections. In areas of the cell where the RNA is needed for essential functions, ribonucleases are prevented from working by inhibitor molecules. But because Amphinase is an amphibian ribonuclease, it can evade the mammalian inhibitor molecules ...

...lled at the chromosomal region called the S locus, which contains numerous alleles that control recognition specificity. These genes code for S-locus ribonucleases (S-RNases), enzymes that degrade RNA. S-RNases are expressed in the stigma, style and ovary and concentrate in the style ECM where they interact with...
