Viruses with RNA Genomes

Viruses with RNA Genomes

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Targets for Drug Action: Overview

Targets for Drug Action: Overview

Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Retroviruses

Retroviruses

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Eukaryotic Transcription Inhibitors

Eukaryotic Transcription Inhibitors

Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a...

Conservation of Protein Domains Over Different Proteins

Conservation of Protein Domains Over Different Proteins

Protein domains are small structurally independent units that are part of a single amino acid chain. Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Multi-species Conserved Sequences

Multi-species Conserved Sequences

Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Background:

Emerging coronaviruses (SARS, MERS, SARS-CoV-2) cause significant global health and economic crises.
Vaccines are slow to develop; antivirals are essential for immediate therapeutic defense against novel viruses.
Coronaviruses are RNA viruses prone to mutations, necessitating continuous development of effective antiviral strategies.

Purpose of the Study:

To review the coronavirus life cycle and existing/developing antiviral therapies.
To identify novel, conserved viral targets for inhibiting emerging coronaviruses.
To propose combination antiviral therapies for pandemic prevention.

Main Methods:

Literature review of coronavirus life cycle and antiviral therapies.
In silico sequence and structure analysis of coronavirus proteins from bat and human hosts.
Identification of conserved and accessible viral protein domains as potential drug targets.

Main Results:

The coronavirus life cycle presents conserved targets for antiviral development.
In silico analysis revealed specific conserved protein domains and residues.
These conserved features represent promising targets for novel antiviral inhibitors.

Conclusions:

Antivirals are the primary therapeutic defense against emerging coronaviruses.
Targeting conserved viral features is key to developing broad-spectrum antivirals.
Combination antiviral therapies are essential for preventing viral outbreaks and pandemics.
