Insulin provokes apparent increases in rat adipocyte M-kinase.
Insulin has been shown to stimulate the translocation of protein kinase C (PKC) in rat adipocytes. Presently, we found that decreases in cytosolic 80 kDa PKC were associated with increases in Ca++/phospholipid-independent protein kinase activity, and increases in a 50 kDa cytosolic protein recognized by anti-PKC antiserum. These findings suggest that insulin provokes increases in M-kinase in rat adipocytes.
