Amino acids 1055 to 1192 in the S2 Region of severe acute respiratory syndrome Coronavirus S Protein induce neutralizing antibodies: Implications for the development of vaccines and antiviral agents

Keng, Choong-Tat; Zhang, Aihua; Shen, Shuo; Lip, Kuo-Ming; Fielding, Burtram C.; Tan, Timothy H.P.; Chou, Chih-Fong; Loh, Chay Boon; Wang, Sifang; Fu, Jianlin; Yang, Xiaoming; Lim, Seng Gee; Hong, Wanjin; Tan, Yee-Joo (American Society for Microbiology, 2005)

The spike (S) protein of the severe acute respiratory syndrome coronavirus (SARS-CoV) interacts with cellular receptors to mediate membrane fusion, allowing viral entry into host cells; hence it is recognized as the primary ...

Characterization of a unique group-specific protein (U122) of the severe acute respiratory syndrome coronavirus

Fielding, Burtram C.; Tan, Yee-Joo; Shen, Shuo; Tan, Timothy H.P.; Ooi, Eng-Eong; Lim, Seng Gee; Hong, Wanjin; Goh, Phuay-Yee (American Society for Microbiology, 2004)

A novel coronavirus (CoV) has been identified as the etiological agent of severe acute respiratory syndrome (SARS). The SARS-CoV genome encodes the characteristic essential CoV replication and structural proteins. Additionally, ...

Genetic lesions within the 3a gene of SARS-CoV

Tan, Timothy H.P.; Barkham, Timothy; Fielding, Burtram C.; Chou, Chih-Fong; Shen, Shuo; Lim, Seng Gee; Hong, Wanjin; Tan, Yee-Joo (BioMed Central, 2005)

A series of frameshift mutations within the 3a gene has been observed in culture-derived severe acute respiratory syndrome coronavirus (SARS-CoV). We report here that viral RNA from clinical samples obtained from SARS-CoV ...

Overexpression of 7a, a Protein Specifically Encoded by the Severe Acute Respiratory Syndrome Coronavirus, Induces Apoptosis via a Caspase-Dependent Pathway

Tan, Yee-Joo; Fielding, Burtram C.; Goh, Phuay-Yee; Shen, Shuo; Tan, Timothy H.P.; Lim, Seng Gee; Hong, Wanjin (American Society for Microbiology, 2004)

Besides genes that are homologous to proteins found in other coronaviruses, the severe acute respiratory syndrome coronavirus genome also contains nine other potential open reading frames. Previously, we have characterized ...

A Novel Severe Acute Respiratory Syndrome Coronavirus Protein, U274, is transported to the Cell Surface and undergoes Endocytosis

Tan, Yee-Joo; Teng, Eileen; Shen, Shuo; Tan, Timothy H.P.; Goh, Phuay-Yee; Fielding, Burtram C.; Ooi, Eng-Eong; Tan, Hwee-Cheng; Lim, Seng Gee; Hong, Wanjin (American Society for Microbiology, 2004)

The severe acute respiratory syndrome coronavirus (SARS-CoV) genome contains open reading frames (ORFs) that encode for several genes that are homologous to proteins found in all known coronaviruses. These are the replicase ...

Cellular Characterization of SARS Coronavirus Nucleocapsid

Goh, Phuay-Yee; Choi, Yook-Wah; Shen, Shuo; Tan, Yee-Joo; Fielding, Burtram C.; Tan, Timothy H.P.; O, Eng-Eong; Lim, Seng Gee; Hong, Wanjin (Leibniz Research Centre for Working Environment and Human Factors, 2004)

The Severe and Acute Respiratory Syndrome coronavirus (SARS CoV) is a newly-emerged virus that caused an outbreak of atypical pneumonia in the winter of 2002-2003. Polyclonal antibodies raised against the nucleocapsid (N) ...

Monoclonal Antibodies targeting the HR2 Domain and the region immediately upstream of the HR2 of the S Protein neutralize in Vitro Infection of Severe Acute Respiratory Syndrome Coronavirus

Lip, Kuo-Ming; Shen, Shuo; Yang, Xiaoming; Keng, Choong-Tat; Zhang, Aihua; Oh, Hsueh-Ling Janice; Li, Zhi-Hong; Hwang, Le-Ann; Chou, Chih-Fong; Fielding, Burtram C.; Tan, Timothy H.P.; Mayrhofer, Josef; Falkner, Falko G.; Fu, Jianlin; Lim, Seng Gee; Hong, Wanjin; Tan, Yee-Joo (American Society for Microbiology, 2006)

We have previously shown that an Escherichia coli-expressed, denatured spike (S) protein fragment of the severe acute respiratory coronavirus, containing residues 1029 to 1192 which include the heptad repeat 2 (HR2) ...

The Severe Acute Respiratory Syndrome Coronavirus 3a Protein Up-Regulates Expression of Fibrinogen in Lung Epithelial Cells

Tan, Yee-Joo; Tham, Puay-Yoke; Chan, Daphne Z. L.; Chou, Chih-Fong; Shen, Shuo; Fielding, Burtram C.; Tan, Timothy H.P.; Lim, Seng Gee; Hong, Wanjin (American Society for Microbiology, 2005)

Here we analyzed the gene expression profile of cells that stably express the severe acute respiratory syndrome coronavirus (SARS-CoV) 3a protein to determine its effects on host functions. A lung epithelial cell-line, ...
