摘要：

A comparative study was made of the extent of phosphorylation of myosin regulatory light chains and C-protein from the left ventricle of the hibernant ground squirrel Citellus undulatus during the periods of hibernation and activity. During hibernation, the light chains were found to be completely dephosphorylated. In active animals, the share of phosphorylated light chains averaged 40-45%. The extent of cardiac C-protein phosphorylation in hibernation was about twice higher than in the active state. Seasonal differences in phosphorylation of the two proteins of ground squirrel myocardium are discussed in the context of adaptation to hibernation. © Nauka/Interperiodica 2006.
