Protein kinase C translocation in relation to proliferative state of C3H 10T1/2 cells

Abstract
Protein kinase C (PKC) activity of cytosol and membrane fractions of 10T cells was studied. In cytosol of fast growing cells PKC activity was found in material eluted with 0.150 M NaCl whereas in membrane fractions activity was eluted with 0.065 and 0.150 M NaCl. In the membrane fraction of confluent cells, in contrast to cytosol, very low PKC activity was observed. The translocation pattern of PKC activity eluted with 0.065 M NaCl may be associated with proliferation.
