    Okadaic acid and dinophysistoxin-1 (35-methylokadaic acid) induced hyperphosphorylation of a 58 kDa protein in primary human fibroblasts, due to inhibition of protein phosphatase 1 and 2A activities. The protein was present in the nuclear and cytosolic fractions. Its pI was 5.3. The hyperphosphorylated protein reacted with monoclonal and polyclonal anti-vimentin antibodies, but not with anti-nucleolin antibody. Phosphorylation of vimentin was stimulated in vitro by dinophysistoxin-1 dose-dependently in the presence of protein phosphatase 2A and protein kinases.
