Codon optimized synthetic plasmids
View Patent ↗One aspect of the current invention is an optimized synthetic mammalian expression plasmid (e.g. pAV0201). This new plasmid comprise a therapeutic element, and a replication element. The therapeutic element of the new plasmid comprises a eukaryotic promoter; a 5′ untranslated region (“UTR”); a codon-optimized-eukaryotic therapeutic gene sequence; and a poly adenylation signal. The therapeutic elements of this plasmid are operatively linked and located in a first operatively-linked arrangement. Additionally, the optimized synthetic mammalian expression plasmid comprises replication elements, wherein the replication elements are operatively linked and located in a second operatively-linked arrangement. The replication elements comprise a selectable marker gene promoter, a ribosomal binding site, and an origin of replication. The first-operatively-linked arrangement and the second-operatively-linked arrangement comprise a circular structure of the codon optimized synthetic mammalian expression plasmid.
1. A synthetic mammalian expression plasmid for plasmid mediated gene supplementation in a species comprising:
(a) a synthetic or eukaryotic promoter comprising SEQ ID NO: 15;
(b) a codon-optimized eukaryotic therapeutic gene sequence comprising SEQ ID NO: 7;
(c) a polyadenylation signal;
(d) a selectable marker gene sequence;
(e) a ribosomal binding site;
(f) a promoter for the selectable marker gene sequence; and
(g) an origin of replication;
wherein the synthetic or eukaryotic promoter, the codon-optimized-eukaryotic therapeutic gene sequence, and the polyadenylation signal comprise therapeutic elements of the synthetic mammalian expression plasmid; the therapeutic elements are operatively linked and located in a first operatively-linked arrangement; the selectable marker gene promoter, the ribosomal binding site, the selectable marker gene sequence, and the origin of replication comprise replication elements of the synthetic mammalian expression plasmid; the replication elements are operatively linked and located in a second-operatively-linked arrangement; and the first-operatively linked arrangement and the second-operatively-linked arrangement comprise a circular structure of the synthetic mammalian expression plasmid.
