GJB5 is so-called Connexin 31.1
PMID:21777377
Cx31.1 (GJB5) is predominantly expressed in the testes and the skin epidermis.
Cx31.1 rarely form functional gap junction channels, either with itself or with other Cx isoforms.
Gap junctions play important roles in various physiologic functions such as regulation of cell proliferation, cell differentiation, tissue development and cell apoptosis.
In most cases, Cxs act as tumour suppressors: Gap junctions play an important role as tumour suppressors in maintaining cell differentiation and preventing transformation
Cx31.1 reduced tumour cell proliferation, anchorage-independent growth, migration and invasion.
Moreover, development of tumours in a xenograft model was suppressed by Cx31.1, suggesting that Cx31.1 may act as a tumour suppressor in NSCLC cell lines.
Expression of Cx31.1 reduced mesenchymal marker vimentin level and increased epithelial marker cytokeratin 18 level, indicating that Cx31.1 may regulate molecular pathways leading to a reverse of the EMT process.

Further studies are required to investigate the mechanism by which Cx31.1 repress cyclin D3 expression

Cx31.1overexpression slightly up-regulated E-cadherin expression, indicating that Cx31.1 overexpression mediate only a partial reversion to an epithelial phenotype of NSCLC cells.
