Cryo-EM structures of pannexin 1 and 3 reveal differences among pannexin isoforms [PDF]
Pannexins are single-membrane large-pore channels that release ions and ATP upon activation. Three isoforms of pannexins 1, 2, and 3, perform diverse cellular roles and differ in their pore lining residues.

Perspectives on the role of Pannexin 1 in neural precursor cell biology
We recently reported that targeted deletion of Pannexin 1 in neural precursor cells of the ventricular zone impairs the maintenance of these cells in healthy and stroke-injured brain. Here we frame this exciting new finding in the context of our previous

Mechanisms of SARS-CoV-2 and Male Infertility: Could Connexin and Pannexin Play a Role?
The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on male infertility has lately received significant attention. SARS-CoV-2, the virus that causes coronavirus disease (COVID-19) in humans, has been shown to impose adverse effects

Contribution of large-pore channels to inflammation induced by microorganisms
Plasma membrane ionic channels selectively permeate potassium, sodium, calcium, and chloride ions. However, large-pore channels are permeable to ions and small molecules such as ATP and glutamate, among others.

Functional implications of calcium permeability of the channel formed by pannexin 1. [PDF]
Although human pannexins (PanX) are homologous to gap junction molecules, their physiological function in vertebrates remains poorly understood. Our results demonstrate that overexpression of PanX1 results in the formation of Ca(2+)-permeable gap ...

Probenecid blocks human P2X7 receptor-induced dye uptake via a pannexin-1 independent mechanism. [PDF]
P2X7 is a ligand-gated ion channel which is activated by ATP and displays secondary permeability characteristics. The mechanism of development of the secondary permeability pathway is currently unclear, although a role for the hemichannel protein ...

Identification of Pannexins in Rat Nasal Mucosa
Pannexins are a second family of gap-junction proteins in vertebrates, classified as pannexin-1, pannexin-2, and pannexin-3. Pannexin-1 is one of the candidates for channel-mediated ATP release into the extracellular space.
