Antibodies to Cardiotin - FocusOn 085

Introduction

Cardiotin is a high molecular weight protein complex (300 kDa) expressed in the myocard of several species and to a lesser extent also in skeletal muscle. Cardiotin is not found in smooth muscle tissues, other mesenchymal or epithelial tissues.

The cardiotin distribution pattern is independent of other sarcomeric components, such as desmin, myosin, actin, titin, nebulin, and desmoplakin, and shows a longitudinal filamentous localization between myofibrils. The cardiotin structure exists of subunits of 60 kDa and 100 kDa containing both the same amino-terminal 14 amino-acid sequence. The tetrameric configuration of the cardiotin protein structure is a transmembrane complex with the N-terminus at the cytoplasmic side of the membrane, able to interact with actin. During cardiac contractile dysfunction, the cardiotin distribution is affected in pathlogical cardiomyocytes i.e. chronic ischemic myocardium. Monoclonal cardiotin antibodies can be used in immunohistochemistry for the detection of a disturbed mitochondrial activity in cardiomyocytes i.e. during chronic ischemia or chronic atrial fibrillation.
