Induction of adipose conversion in 3T3-L1 cells is associated with an early phosphorylation of a protein partly homologous with mouse vimentin.
Induction of adipose conversion in 3T3-L1 by bezafibrate has been previously shown to be enhanced by dibutyryl cAMP and to be associated with an early phosphorylation of a 60 kDa acidic protein [Biochim. Biophys. Acta 1054 (1990) 219-224; FEBS Lett. 285 (1991) 63-65]. We describe here the isolation and sequencing of two peptides of the protein concerned. Both appear to be homologous with two respective amino acid sequences of the mouse intermediate filament protein vimentin.
