Factor H vectors and uses thereof
Aspects of the disclosure relate to compositions and methods for expressing a Factor H protein (or a variant thereof) in a cell or subject. In some embodiments, the disclosure provides isolated nucleic acids and rAAVs comprising a transgene encoding a Factor H protein variant and one or more regulatory sequences. In some embodiments, compositions described herein are useful for treating subjects having diseases associated with Factor H deficiency.
1 . An isolated nucleic acid encoding the amino acid sequence set forth in SEQ ID NO: 3, wherein the nucleic acid sequence is operably linked to SEQ ID NO: 19 and SEQ ID NO: 14, and further comprises a promoter comprising the nucleic acid sequence set forth in SEQ ID NOs: 10 and 12.
2 . The isolated nucleic acid of claim 1 , wherein the nucleic acid comprises the sequence set forth in SEQ ID NO: 4.
3 . The isolated nucleic acid of claim 1 , wherein the promoter further comprises an enhancer sequence, wherein the enhancer sequence comprises the sequence set forth in SEQ ID NO: 9 or 10.
4 . The isolated nucleic acid of claim 1 , wherein the isolated nucleic acid comprises one or more introns.
5 . The isolated nucleic acid of claim 4 , wherein at least one intron is positioned between the promoter and the nucleic acid sequence.
6 . The isolated nucleic acid of claim 4 , wherein at least one intron comprises the sequence set forth in any one of SEQ ID NOs: 13-15.
7 . The isolated nucleic acid of claim 1 further comprising a 3′ untranslated region (3′UTR).
8 . The isolated nucleic acid of claim 7 , wherein the 3′UTR comprises the sequence set forth in SEQ ID NO: 17 or 18.
9 . A vector comprising the isolated nucleic acid of claim 1 .
10 . The vector of claim 9 , wherein the vector is a plasmid or a viral vector.
11 . The vector of claim 10 , wherein the viral vector is an adenoviral vector, adeno-associated virus vector, a lentiviral vector, a retroviral vector, or a Baculovirus vector.
12 . A host cell comprising the vector of claim 9 .
13 . The host cell of claim 12 , wherein the host cell is a mammalian cell, yeast cell, bacterial cell, or insect cell.
14 . A recombinant adeno-associated virus (rAAV) comprising:
(i) the isolated nucleic acid of claim 1 ; and
(ii) an adeno-associated virus (AAV) capsid protein.
15 . The rAAV of claim 14 , wherein the capsid protein has a tropism for muscle tissue or ocular tissue.
16 . The rAAV of claim 14 , wherein the capsid protein is of a serotype selected from AAV1, AAV2, AAV3, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, or a variant thereof.
