Abstract

We have characterized 95% (4,404 nucleotides) of the genome of adeno-associated virus type 5 (AAV5), including part of the terminal repeats and the terminal resolution site. Our results show that AAV5 is different from all other described AAV serotypes at the nucleotide level and at the amino acid level. The sequence homology to AAV2, AAV3B, AAV4, and AAV6 at the nucleotide level is only between 54 and 56%. The positive strand contains two large open reading frames (ORFs). The left ORF encodes the nonstructural (Rep) proteins, and the right ORF encodes the structural (Cap) proteins. At the amino acid level the identities with the capsid proteins of other AAVs range between 51 and 59%, with a high degree of heterogeneity in regions which are considered to be on the exterior surface of the viral capsid. The overall identity for the nonstructural Rep proteins at the amino acid level is 54.4%. It is lowest at the C-terminal 128 amino acids (10%). There are only two instead of the common three putative Zn fingers in the Rep proteins. The Cap protein data suggest differences in capsid surfaces and raise the possibility of a host range distinct from those of other parvoviruses. This may have important implications for AAV vectors used in gene therapy.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • AAV5 has the most distinct sequence of the capsids (61.2% identity to AAV2; AAV8 83.6%; AAV9 82.7%).

    “AAV5 has the most distinct sequence of the capsids (AAV5: 61.2% amino acid sequence identity to AAV2, AAV8: 83.6% amino acid sequence identity to AAV2, AAV9: 82.7% sequence identity to AAV2),55,56”

    From Antibody neutralization poses a barrier to intravitreal adeno-associated viral vector gene delivery to non-human primates (2015) · cites this paper as [56]

    The capsid-alignment results and Table 1 support that AAV5 is distinct from the serotypes this paper compared. But Table 1 gives 58.3% identity for AAV5 versus AAV2, not 61.2%, and the paper does not report the claimed AAV8 or AAV9 comparisons (page numbers unavailable in our copy). (LLM, conf=0.90)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
