nuclear chaperone nucleophosmin, a proposed oncogenic protein that is overexpressed in many different human tumors. avrainvillamide 30-49 nucleophosmin 1 Homo sapiens 145-158 17958425-4 2007 Affinity-isolation of nucleophosmin was inhibited in the presence of iodoacetamide (10 mM), free (+)-avrainvillamide (100 microM), and a series of closely related structural analogues of (+)-avrainvillamide, the latter with inhibitory effects that appear to correlate with measured growth-inhibitory potencies. avrainvillamide 97-116 nucleophosmin 1 Homo sapiens 22-35 17958425-4 2007

Site-directed mutagenesis of each of the three cysteine residues of a truncated nucleophosmin coexpressed with native nucleophosmin in COS-7 cells revealed that the mutation cys275 --> ala275 effectively and uniquely reduced affinity-isolation of the truncated protein, suggesting that avrainvillamide targets cys275 of nucleophosmin. avrainvillamide 289-304 nucleophosmin 1 Homo sapiens 80-93 17958425-7 2007 Finally, we show that treatment of adhered LNCaP or T-47D cells with (+)-avrainvillamide leads to an increase in cellular p53 concentrations, and that siRNA-promoted depletion of nucleophosmin in a population of HeLa S3 cells leads to increased sensitivity of that population toward apoptotic death upon treatment with (+)-avrainvillamide. avrainvillamide 69-88 tumor protein p53
