In silico comparative analysis of SARS-CoV-2 Nucleocapsid (N) protein using bioinformatics tools

چکیده
The world has been encountered to one of the biggest pandemics that causing by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 is placed in Beta-CoV genus Coronaviridae family. N protein crucial structural proteins binds genome thereby generating helical ribonucleoprotein core. It involved viral transcription/replication, translation, and assembly after entering host cell through interacting with proteins. sequences taxonomically related CoVs are examined using bioinformatics tools approaches including sequence alignment, phylogenetic analyzes, predicting putative N-Glycosylation phosphorylation positions also predictions comparative analyzes performed on 3D structures from some applied analyzes. Results mega BLAST search revealed most similar Bat-CoV RaTG13 CoVs. grouped SARS, pangolin, civet bat (RATG13, SL ZC45 ZXC21) protein, nucleotide based ML trees. Some were showed divergence other analyzed due amino acid substitutions detected samples highest Richmont/USA (QJA42209.1) Greece (QIZ16579.1) samples, 3 place substitutions, respectively. By domain three domains as Corona_nucleocora (Pfam), terminal CoV RNA-binding (HAMAP) C dimerization (HAMAP). Possible N-glycosylation predicted at two positions. Assessments possible serine, threonine tyrosine phosphorylations found be 100 positions, 34 them higher than 80% possibility. structure analysis TM scores although results shown consistency taxonomy CoVs, not same fold.

The Epitope Study on the SARS-CoV Nucleocapsid Protein
The nucleocapsid protein (N protein) has been found to be an antigenic protein in a number of coronaviruses. Whether the N protein in severe acute respiratory syndrome-associated coronavirus (SARS-CoV) is antigenic remains to be elucidated. Using Western blot and Enzyme-linked Immunosorbent Assay (ELISA), the recombinant N proteins and the synthesized peptides derived from the N protein were sc...

BACKGROUND Severe acute respiratory syndrome (SARS)-CoV is a newly emerging virus that causes SARS with high mortality rate in infected people. Successful control of the global SARS epidemic will require rapid and sensitive diagnostic tests to monitor its spread, as well as, the development of vaccines and new antiviral compounds including neutralizing antibodies that effectively prevent or tre...
متن کاملSARS-CoV Genome Polymorphism: A Bioinformatics Study
A dataset of 103 SARS-CoV isolates (101 human patients and 2 palm civets) was investigated on different aspects of genome polymorphism and isolate classification. The number and the distribution of single nucleotide variations (SNVs) and insertions and deletions, with respect to a "profile", were determined and discussed ("profile" being a sequence containing the most represented letter per pos...
متن کاملIn silico design a multivalent epitope vaccine against SARS-CoV-2 for Iranian populations
Background: Due to high genetic variation in human leukocyte antigen )HLA( alleles, epitope-based vaccines don’t show equal efficacy in different human populations. therefore, we proposed a multi-epitope vaccine against SARS-CoV-2 for Iranian populations. Materials and Methods: For this purpose, the proteins without allergenicity and high antigenicity as well as conservancy level from SARS-CoV...
متن کاملPrior immunization with severe acute respiratory syndrome (SARS)-associated coronavirus (SARS-CoV) nucleocapsid protein causes severe pneumonia in mice infected with SARS-CoV.
The details of the mechanism by which severe acute respiratory syndrome-associated coronavirus (SARS-CoV) causes severe pneumonia are unclear. We investigated the immune responses and pathologies of SARS-CoV-infected BALB/c mice that were immunized intradermally with recombinant vaccinia virus (VV) that expressed either the SARS-CoV spike (S) protein (LC16m8rVV-S) or simultaneously all the stru...
