Characterization and expression of an mRNA encoding a wound
... Both strands of the cDNA for TAB7 were fully sequenced. The encoded mRNA is 694 nucleotides in length with an open reading frame (ORF) of 201 amino acids. The largest ORF does not begin with an initiation codon and is therefore not full length (Fig. 2). Further screening of the cDNA library failed t ...

Rapid RNA Exchange in Aqueous Two-Phase System and Coacervate Droplets Christian Hentrich
... Although our FRAP measurements report only on the entry of RNA oligomers into ATPS or coacervate droplets, at steady state, the rate of efflux of RNA from droplets must equal the rate of influx. Our data therefore imply that RNA molecules do not remain localized within any droplet for longer than a ...
