Cardiac myocytes express multiple gap junction proteins.
Electrical propagation in the normal heart occurs via intercellular transfer of current at gap junctions. Alterations in intercellular coupling in the diseased heart are critical in the pathogenesis of reentrant ventricular arrhythmias. Until recently only a single gap junction protein was known to couple cardiac myocytes. We have now identified and sequenced two additional distinct gap junctio...
متن کاملHigh resolution map of Caenorhabditis elegans gap junction proteins.
The innexin family of gap junction proteins has 25 members in Caenorhabditis elegans. Here, we describe the first high-resolution expression map of all members through analysis of live worms transformed with green fluorescent protein under the control of entire promoter regions. Our analyses show that innexins have dynamic expression patterns throughout development and are found in virtually al...
متن کاملGap junction proteins and their role in spinal cord injury
Gap junctions are specialized intercellular communication channels that are formed by two hexameric connexin hemichannels, one provided by each of the two adjacent cells. Gap junctions and hemichannels play an important role in regulating cellular metabolism, signaling, and functions in both normal and pathological conditions. Following spinal cord injury (SCI), there is damage and disturbance ...
متن کاملPannexins, a family of gap junction proteins expressed in brain.
Database search has led to the identification of a family of proteins, the pannexins, which share some structural features with the gap junction forming proteins of invertebrates and vertebrates. The function of these proteins has remained unclear so far. To test the possibility that pannexins underlie electrical communication in the brain, we have investigated their tissue distribution and fun...
متن کاملGap junction proteins in the light-damaged albino rat
PURPOSE Changes in connexin expression are associated with many pathological conditions seen in animal models and in humans. We hypothesized that gap junctions are important mediators in tissue dysfunction and injury processes in the retina, and therefore, we investigated the pattern of connexin protein expression in the light-damaged albino rat eye. METHODS Adult Sprague-Dawley rats were exp...
