HighlightsIntroduction of PANX2
Pannexin 2 (PANX2), encoded by the PANX2 gene in humans, is a member of pannexin family. PANX2 is a membrane protein with 4 transmembrane domains and a cytoplasmic N and C termini. PANX2 can be detected in the eye, thyroid, prostate, kidney, liver, spinal cord and brain, including cortex, striatum, olfactory bulb, hippocampus, thalamus, and cerebellum. PANX2 gene is mapped to chromosome 22q13. There are multiple transcript variants encoding different isoforms have been found for this gene.

Function of PANX2 Membrane Protein
As the structural component of gap junctions, PANX2 can combine with PANX1 or by itself to form cell type-specific gap junctions with distinct properties. PANX2 is capable of forming large pore channels that allow the passage of ions and macromolecules involved in paracrine and autocrine signaling. By interacting with PANX1, PANX2 can form heteromeric channels with reduced channel properties compared to homomeric ones. Recent studies show that N-glycosylation is necessary for proper processing of PANX2 at the endoplasmic reticulum, regulating its intracellular distribution, but it is not required for interacting with PANX1. PANX2 is identified as a novel target gene of miR-423-3p, and the knockdown of PANX2 attenuates the effects of miR-423-3p inhibition on glioma cell proliferation and apoptosis. So, up-regulation of PANX2 may be a potential approach to inhibit glioma growth by targeting miR-423-3p.

Application of PANX2 Membrane Protein in Literature
In this article, the authors reveal that targeting miR-423-3p may inhibit glioma growth via the upregulation of PANX2.
This article indicates that N-glycosylation is important for folding and trafficking of Panx2, and the un-glycosylated Panx2 can readily interact with Panx1 to regulate their localization and potentially their channel function in cells.
This article suggests that Panx2 is an important regulator of the insulin secretory capacity and apoptosis in pancreatic β-cells.
This article reveals the dense expression of Panx2 in the enteric nervous system and the co-localization of Panx2 with a spectrum of neuronal markers, indicating that Panx2 may be involved in mediating neurotransmission in the colon.
This report demonstrates that the endogenous expression of Panx2 protein is not restricted to the CNS and can also be expressed in other tissues such as skin, kidney, and liver through real-time qPCR, Western blotting and immunofluorescence test.
