Evidence for the presence of DNase-actin complex in L1210 leukemia cells
FEBS Letters
|March 7, 1983
Abstract:
L1210 leukemia cell cytosol was analysed for the presence of DNase I activity. No free activity was determined in crude cytosol. DNase I enzyme was found to occur in a latent form bound to cytoplasmic actin. DNase-actin complex was partially isolated by Sephadex filtration and DNase I-like activity was demonstrated after SDS gel electrophoresis of the complex and enzyme renaturation. The results were compared with those for synthetic complex of pancreatic bovine DNase I and chicken muscle actin.
