Abstract:
:We report the half-lives for two proteins involved in the regulation of intracellular calcium in the brain: the plasma membrane Ca-ATPase and its regulatory protein, calmodulin. [14C]-labeled leucine was injected into seven month old adult Fischer 344 rats and the time-dependent appearance and loss of radioactivity was monitored in both the serum and proteins from the brains of rats sacrificed from 4 hours to 13 days after injection. Experimental data obtained for calmodulin and the plasma membrane Ca-ATPase are best described by theoretical curves accounting for leucine reutilization that assume apparent half-lives of 18 (+/-2) hours and 12 (+/-1) days, respectively.
