Connexin proteins are short-lived within the cell, whether present in the secretory pathway or in gap junction plaques. Their levels can be modulated by their rate of degradation. Connexins, at different stages of assembly, are degraded through the proteasomal, endo-/lysosomal, and phago-/lysosomal pathways. In this review, we summarize the current knowledge about connexin and gap junction degradation including the signals and protein-protein interactions that participate in their targeting for degradation.

Craniometaphyseal dysplasia (CMD), a rare craniotubular disorder, occurs in an autosomal dominant (AD) or autosomal recessive (AR) form. CMD is characterized by hyperostosis of craniofacial bones and metaphyseal flaring of long bones. Many patients with CMD suffer from neurological symptoms.

A rare haplotype of the GJD3 gene segregating in familial Meniere's disease interferes with connexin assembly.

Genome Med

Background: Familial Meniere's disease (FMD) is a rare polygenic disorder of the inner ear. Mutations in the connexin gene family, which encodes gap junction proteins, can also cause hearing loss, but their role in FMD is largely unknown.

Methods: We retrieved exome sequencing data from 94 individuals in 70 Meniere's disease (MD) families.

Gap junction intercellular communications regulates activation of SARM1 and protects against axonal degeneration.

Sterile alpha and Toll/interleukin-1 receptor motif containing 1 (SARM1), a nicotinamide adenine dinucleotide (NAD)-utilizing enzyme, mediates axon degeneration (AxD) in various neurodegenerative diseases. It is activated by nicotinamide mononucleotide (NMN) to produce a calcium messenger, cyclic ADP-ribose (cADPR). This activity is blocked by elevated NAD level.

The Unexplored Role of Connexin Hemichannels in Promoting Facioscapulohumeral Muscular Dystrophy Progression.

DUX4 is typically a repressed transcription factor, but its aberrant activation in Facioscapulohumeral Muscular Dystrophy (FSHD) leads to cell death by disrupting muscle homeostasis. This disruption affects crucial processes such as myogenesis, sarcolemma integrity, gene regulation, oxidative stress, immune response, and many other biological pathways. Notably, these disrupted processes have been associated, in other pathological contexts, with the presence of connexin (Cx) hemichannels-transmembrane structures that mediate communication between the intracellular and extracellular environments.

Tracheal tuft cells shape immune responses in the airways. While some of these effects have been attributed to differential release of either acetylcholine, leukotriene C4 and/or interleukin-25 depending on the activating stimuli, tuft cell-dependent mechanisms underlying the recruitment and activation of immune cells are incompletely understood. Here we show that Pseudomonas aeruginosa infection activates mouse tuft cells, which release ATP via pannexin 1 channels.
