Mind the Gap; Regulation of Gap Junctional, Intercellular Communication by the Src Oncogene Product and its Effectors

Gap junctions are channels that connect the interiors of neighboring cells and are formed by the connexin (Cx) proteins. A reduction in gap junctional, intercellular communication (GJIC) often correlates with increased growth and neoplastic transformation. Cx43 is a widely expressed connexin which can be phosphorylated by the Src oncoprotein tyrosine kinase on tyr247 and -265, and this reduces
