N2 - Acyl-CoA-binding protein (ACBP), also named diazepam-binding inhibitor or endozepine, is a 10 kDa protein for which a surprisingly large number of biological activities has been suggested. Some of these would seem to require a rapid intracellular turnover of the protein. In this paper we report on the turnover of ACBP in cell lines derived from mouse, rat and man. ACBP was identified in two-dimensional gels by using specific antibodies. Cells were labelled with [35S]methionine and chased for various periods of time. Total protein was extracted, subjected to two-dimensional PAGE, and radioactivity in the spot containing ACBP was determined by liquid-scintillation counting. ACBP half-life was determined, and varied from 25 to 53 h depending on the cell line and the growth conditions. In all cases, radioactivity in ACBP was lost slightly faster than radioactivity in total protein. These results are discussed in relation to the possible function suggested for ACBP.
