Description

General description

Pannexin-1 (UniProt: Q9JIP4) is encoded by the Panx1 gene (Gene ID: 55991) in murine species. Pannexin-1 is a multi-pass membrane protein of the pannexin family that serves as a high-conductance, voltage-gated channel. It is widely expressed, including in cartilage, skin, spleen, heart, and brain. In the nervous system Panx1 transcripts have been detected in the cerebellum, cortex, lens, retina, pyramidal cells, interneurons of the neocortex and hippocampus. Three pannexin family genes (PANX1-3) have been identified in murine and human genomes. Pannexins share structural and functional similarities and play important roles in several physiological processes, including ATP release, Ca2+ homeostasis, and synaptic neurotransmitters release. Pannexins can also form intermixed channels and the intermixing is more evident between Pannexin 1 and 2. The level of intermixing is governed by the degree of N-glycosylation. Post-translational N-glycosylation plays a role in cell surface targeting. Pannexin-1 can also undergo S-nitrosylation, which can inhibit channel currents and ATP release. It has been shown that Pannexin-1 channel can release ATP in response to activation by TNF-alpha that requires activation of type-1 TNF receptors and downstream signaling through Src family kinases (SFK). Tryosine 198 in the intracellular loop region of Pannexin-1 is highly conserved and is considered as a SFK phosphorylation site. Pannexin-1 has been linked to propagation of calcium waves, regulation of vascular tone, taste-bud function, and in tumor suppression in gliomas. Pannexin-1 channel opening can contribute to cell death and seizures under ischemic or epileptic conditions. (Ref.: Penuela, S et al. (2013). Biochim. Biophys. Acta 1828(11); 15-22).
