The invention relates to compositions and methods for the preparation, manufacture and therapeutic use of polynucleotides, primary transcripts and mmRNA molecules.
1 . A method of producing a polypeptide of interest in a mammalian cell or tissue comprising contacting said mammalian cell or tissue with a modified mRNA, wherein said modified mRNA encodes dolichyl-phosphate (UDP-N-acetylglucosamine) N-acetylglucosaminephosphotransferase 1 (GlcNAc-1-P transferase) (SEQ ID NO: 9985) and wherein said modified mRNA comprises modifications selected from the group consisting of:
(a) 5-methylcytosine and 2-thiouridine,
(b) pseudouridine and 5-methylcytosine, and
(c) 1-methylpseudouridine.
2 . The method of claim 1 , wherein the modified mRNA comprises the modification 1-methylpseudouridine and further comprises the modification 5-methylcytosine.
3 . The method of claim 1 , wherein the modified mRNA comprises the modifications 5-methylcytosine and 2-thiouridine, wherein 25% of the cytosine residues in the modified mRNA are 5-methylcytosines and 25% of the uridine residues in the modified mRNA are 2-thiouridine.
4 . The method of claim 1 , wherein at least one of the 5′ untranslated region or the 3′ untranslated region of the modified mRNA is not derived from beta-globin.
5 . A modified mRNA encoding a polypeptide of interest, said polypeptide of interest is dolichyl-phosphate (UDP-N-acetylglucosamine) N-acetylglucosaminephosphotransferase 1 (GlcNAc-1-P transferase) (SEQ ID NO: 9985) and wherein said modified mRNA comprises modifications selected from the group consisting of:
(a) 5-methylcytosine and 2-thiouridine,
(b) pseudouridine and 5-methylcytosine, and
(c) 1-methylpseudouridine.
6 . The modified mRNA of claim 5 , wherein the modified mRNA comprises the modification 1-methylpseudouridine and further comprises the modification 5-methylcytosine.
