Supplementary information

Connexin 32 also known as GJB1 is a gap junction protein with a molecular mass of approximately 32 kDa. This protein facilitates direct intercellular communication by forming gap junction channels that allow ions and small molecules to pass between adjacent cells. Connexin 32 is expressed in various tissues including liver pancreas and many types of epithelial cells. Its expression ensures cells can synchronize their activities important for maintaining tissue homeostasis.
Biological function summary

Connexin 32 plays a significant role in maintaining cellular communication networks. This protein forms hexameric complexes called connexons which dock with connexons of adjacent cells to create functional gap junction channels. These channels are essential in processes such as maintaining homeostasis cell differentiation and synchronized contraction of tissues like cardiac muscle. The structural formation allows direct transfer of metabolites and signaling molecules highlighting its importance in multicellular organism function.

Pathways

Connexin 32 actively contributes to cellular communication and metabolic coordination. It participates in the phosphoinositide 3-kinase (PI3-K) pathway and the ERK/MAPK signaling pathway which are important for cell growth proliferation and apoptosis. Connexin 32 interacts with proteins like Connexin 43 with both proteins playing roles in channel assembly and intracellular signaling processes that influence cellular responses to external stimuli.

Connexin 32's dysfunction aligns with specific neuropathies. Mutations in the GJB1 gene often lead to X-linked Charcot-Marie-Tooth disease a disorder affecting peripheral nerves. This disease involves degeneration of nerve fibers disrupting muscle function and sensation and connects with proteins that share functional pathways like PMP22. Additionally Connexin 32 has implications in liver diseases where its reduced expression correlates with disrupted hepatocyte communication affecting liver function and regeneration.
