International Journal of Molecular Sciences, 2023 Mpox or monkeypox virus (MPXV) belongs to the subclass of Poxviridae and has emerged recently as a global threat. With a limited number of anti-viral drugs available for this new virus species, it is challenging to thwart the illness it begets. Therefore, characterizing new drug targets in the virus may prove advantageous to curbing the disease.

Coronavirus viroporins: structure and function [PDF]
The Ukrainian Biochemical Journal, 2021 Viroporins are involved in viral pathogenesis, play an important role in the morphogenesis of virions and ensure their release from the infected cell. These proteins are potentially promising as possible targets for the regulation of virus reproduction.

Viroporins in the Influenza Virus [PDF]
Cells, 2019 Influenza is a highly contagious virus that causes seasonal epidemics and unpredictable pandemics. Four influenza virus types have been identified to date: A, B, C and D, with only A–C known to infect humans. Influenza A and B viruses are responsible for seasonal influenza epidemics in humans and are responsible for up to a billion flu infections ...

Viroporins: structure and biological functions [PDF]
Nature Reviews Microbiology, 2012 Viroporins are small, hydrophobic proteins that are encoded by a wide range of clinically relevant animal viruses. When these proteins oligomerize in host cell membranes, they form hydrophilic pores that disrupt a number of physiological properties of the cell. Viroporins are crucial for viral pathogenicity owing to their involvement in several diverse

Discovery and Characterization of the Phospholemman/SIMP/Viroporin Superfamily [PDF]
Microbial Physiology, 2022 Using bioinformatic approaches, we present evidence of distant relatedness among the Ephemerovirus Viroporin family, the Rhabdoviridae Putative Viroporin U5 family, the Phospholemman family, and the Small Integral Membrane Protein family. Our approach is based on the transitivity property of homology complemented with five validation criteria: (1 ...

Membrane Integration of Poliovirus 2B Viroporin [PDF]
Journal of Virology, 2011 ABSTRACT Virus infections can result in a variety of cellular injuries, and these often involve the permeabilization of host membranes by viral proteins of the viroporin family. Prototypical viroporin 2B is responsible for the alterations in host cell membrane permeability that take place in enterovirus-infected cells. 2B protein
