缝隙连接蛋白与房室结

摘要

Atrioventricular node is responsible for conducting impulse from atria to ventricles.Connexin within atri-oventricular junction play a key role in conducting function of atrioventricular junction;because it presents diversi-fied expression,so its conducting junction is diversified in different areas of atrioventricular junction.Knowing ex-pression type of connexins can approximately determine conductive function in atrioventricular junction area.%房室结负责将冲动从心房传递到心室。房室交界区内缝隙连接蛋白在其传导中发挥着关键的作用，又因其表达呈多样化，决定房室交界区不同部位的传导功能不同。明确缝隙连接蛋白的表达类型可大致确定房室交界区域的传导功能。
