Ca++／CalmodulindependentProteinKinaseActivation
The calcium/calmodulin-dependent kinases (CaMKs) are involved in a large number of cellular responses induced by hormones, neurotransmitters and other signalling. Elevation of calcium functions as a major second messenger, where the intracellular concentration of calcium can be maintained at extremely low levels and susequently increased following specific calcium-mobilizing stimuli. There are many buffers to the cal......阅读全文
