Studies of the gene-edited mice showed their TLR7 protein is activated simply by encountering the molecule guanosine, which is present in the DNA and RNA of healthy human cells, her team reports today.

They found that sugar groups called N-linked glycans bind to a subset of RNAs through one of their chemical letters called guanosine.

Instead, ABP1 functions at the cell surface to bind auxin and a family of membrane kinases, thereby activating intracellular guanosine triphosphatases to initiate important developmental changes in cell shape.

In addition, we have sought to determine whether identified transcripts are modified at their 5′ and 3′ termini by the presence of a 7-methyl guanosine cap or polyadenylation, respectively.
