We constructed gfph, a synthetic version of the jellyfish Aequorea victoria
green fluorescent protein (gfp) cDNA that is adapted for high- level
expression in mammalian cells, especially those of human origin. A total of
92 base substitutions were made in 88 codons in order to change the codon
usage within the gfp10 coding sequence so that it was more appropriate for
expression in mammalian cells. We also describe a series of versatile
recombinant adeno-associated virus and adenovirus vectors for delivery and
expression of genes into mammalian cells and, using these vectors,
demonstrate the efficient transduction and expression of the gfph gene in
the human cell line 293 and also in vivo, within neurosensory cells of
guinea pig eye. Cells infected with recombinant adeno-associated virus-GFPH
can be readily sorted by fluorescence-activated cell sorting, suggesting
that the newly designed gfph gene could be widely used as a reporter in
many gene delivery technologies, including human gene therapy.
