Complete genome sequence of bat coronavirus HKU2 from Chinese horseshoe bats revealed a much smaller spike gene with a different evolutionary lineage from the rest of the genome
Open accessAbstract
Apart from bat-SARS-CoV, we have identified a novel group 1 coronavirus, bat-CoV HKU2, in Rhinolophus sinicus (Chinese horseshoe bats). Since it has been suggested that the receptor-binding motif (RBM) of SARS-CoV may have been acquired from a group 1 coronavirus, we conducted a surveillance study and identified bat-SARS-CoV and bat-CoV HKU2 in 8.7% and 7.5% respectively of R. sinicus in Hong Kong and Guangdong. Complete genome sequencing of four strains of bat-CoV HKU2 revealed the smallest coronavirus genome (27164 nucleotides) and a unique spike protein evolutionarily distinct from the rest of the genome. This spike protein, sharing similar deletions with other group 2 coronaviruses in its C-terminus, also contained a 15-amino acid peptide homologous to a corresponding peptide within the RBM of spike protein of SARS-CoV, which was absent in other coronaviruses except bat-SARS-CoV. These suggest a common evolutionary origin in the spike protein of bat-CoV HKU2, bat-SARS-CoV, and SARS-CoV.

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.
