Summary
This review details how SARS-CoV-2 proteins interact with host metabolism, impacting COVID-19 pathogenesis. It focuses on experimentally confirmed functions of viral proteins and targeted host pathways like immune response and gene expression.
Area of Science:
- Virology
- Molecular Biology
- Immunology
Background:
- The COVID-19 pandemic necessitates a deep understanding of SARS-CoV-2 biology.
- SARS-CoV-2 protein interactions with host metabolism are critical for disease development.
- Existing reviews often focus on the spike protein or therapeutics, leaving a gap in understanding other viral proteins.
Purpose of the Study:
- To review experimentally confirmed functions of SARS-CoV-2 non-structural, accessory, and structural proteins.
- To identify host mechanisms primarily targeted by SARS-CoV-2 proteins.
- To highlight the multifaceted roles of viral proteins and areas needing further research.
Main Methods:
- Literature review focusing exclusively on SARS-CoV-2.
- Summarization of findings on 16 non-structural, 6 accessory, and 4 structural proteins.
- Exclusion of extensive discussion on spike protein and therapeutics.
Main Results:
- SARS-CoV-2 proteins target key host pathways including gene expression and immune responses (e.g., ribosome translation, JAK/STAT, RIG-1/MDA5, NF-κB).
- Viral proteins exhibit diverse functions, with varying levels of information available for each.
- Specific interactions and their consequences for host cell machinery are elucidated.
Conclusions:
- Understanding SARS-CoV-2 protein functions is crucial for comprehending COVID-19 pathogenesis.
- Targeting host pathways by viral proteins is a key mechanism of infection.
- Further research is needed to fully elucidate the roles of all SARS-CoV-2 proteins.

5.2K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

02:50Conjugated Proteins
18.3K
Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

01:33Coat Assembly and GTPases
3.5K
Vesicles incorporate different coat protein subunits in different cell locations, which changes the properties of the coat, such as the shape and geometry of the transport vesicles. Thus, vesicle coat proteins also play a significant role in cargo selection.
Coat assembly depends on the local availability of phosphatidylinositol phosphates or PIPs and GTP-binding proteins. Adaptor proteins, which link the coat proteins to the membrane, bind to these PIPs and play a crucial role in controlling...

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

5.1K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

00:56Viral Structure
62.4K
Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.
