WebProtein trafficking, for ion channels, encompasses the correct formation and delivery of channels to their appropriate membrane subdomain. Altered trafficking is a dangerous consequence of diseased myocardium. Regulation of protein trafficking and its restoration in diseased myocardium presents opportunities for novel therapeutic development. WebAt the department of Medical Physiology, we focus on trafficking of the repolarizing ion channels that underlie IKr and IK1. We are beginning to learn that ion channels traffic in channel-specific pathways using particular interacting proteins that target them to their destination membranes. small table top dishwashers uk https://boatshields.com
