A Human-Derived Monoclonal Antibody Targeting Extracellular Connexin Domain Selectively Modulates Hemichannel Function [PDF]
, 2019 Connexin hemichannels, which are plasma membrane hexameric channels (connexons) composed of connexin protein protomers, have been implicated in a host of physiological processes and pathological conditions. A number of single point pathological mutations

Connexins : substrates and regulators of autophagy [PDF]
, 2016 Connexins mediate intercellular communication by assembling into hexameric channel complexes that act as hemichannels and gap junction channels. Most connexins are characterized by a very rapid turn-over in a variety of cell systems.

Connexin43 and Ischemic Preconditioning [PDF]
Cardiovascular Research, 2004 Connexin43 (Cx43) is the essential protein to form hemichannels and gap junctions in the myocardium. The phosphorylation status of Cx43 which is regulated by a variety of protein kinases and phosphatases determines hemichannel and/or gap junction conductance and permeability.

What's the Function of Connexin 32 in the Peripheral Nervous System? [PDF]
, 2018 Connexin 32 (Cx32) is a fundamental protein in the peripheral nervous system (PNS) as its mutations cause the X-linked form of Charcot-Marie-Tooth disease (CMT1X), the second most common form of hereditary motor and sensory neuropathy and a demyelinating

Expression of connexins in human preimplantation embryos in vitro [PDF]
, 2004 Intercellular communication via gap junctions is required to coordinate developmental processes in the mammalian embryo. We have investigated if the connexin (Cx) isoforms known to form gap junctions in rodent preimplantation embryos are also expressed ...

Connexin-43 Hemichannels Opened by Metabolic Inhibition [PDF]
Journal of Biological Chemistry, 1999 The cause of altered ionic homeostasis leading to cell death during ischemia and metabolic inhibition is unclear. Hemichannels, which are precursors to gap junctions, are nonselective ion channels that are permeable to molecules of less than Mr 1000.

Connexin 43 Hemichannels Are Permeable to ATP [PDF]
The Journal of Neuroscience, 2008 Astrocytes are electrically nonexcitable cells that communicate by means of Ca2+signaling. Long-distance intercellular Ca2+waves are initiated by release of ATP and activation of purinergic receptors on nearby cells. Previous studies have implicated connexin 43 (Cx43) in ATP release, but definitive proof that ATP exits through Cx43 hemichannels does ...

Osteocytic connexin 43 channels affect fracture healing
Journal of Cellular Physiology, 2019 AbstractThe cross‐talk between cells is very critical for moving forward fracture healing in an orderly manner. Connexin (Cx) 43‐formed gap junctions and hemichannels mediate the communication between adjacent cells and cells and extracellular environment. Loss of Cx43 in osteoblasts/osteocytes results in delayed fracture healing. For investigating the

Internal translation of the connexin 43 transcript [PDF]
Cell Communication and Signaling, 2014 Connexin 43 (Cx43), the most widely expressed gap junction protein, is associated with a number of physiological and pathological conditions. Many functions of Cx43 have been shown to be independent of gap junction formation and only require the expression of Cx43 C-terminal fragments.

Connexin Expression in Human Minor Salivary Glands: An Immunohistochemical Microscopy Study
Molecules, 2022 Connexins (Cxs) are transmembrane proteins involved in the formation of hemichannels and gap junctions (GJs). GJs are involved in various physiological functions, including secretion in glandular tissue. It has been demonstrated that Cx26, Cx32, and Cx43
