We have identified a cisplatin-inducible gene, the mitochondrial ribosomal protein S11 (MRP S11) gene, by means of mRNA differential display. Functional analysis of the MRP S11 promoter showed that a Staf binding site in the promoter is required for both basal promoter activity and cisplatin-inducible activity. We also found that Staf binding activity is significantly increased in nuclear extracts from cells treated with cisplatin. ZNF 143 and ZNF 76 are human homologues of the Xenopus transcriptional activator, Staf. ZNF 143 expression is induced by cisplatin but ZNF 76 expression is not. However, ZNF 143 expression is not induced by transplatin, which is clinically ineffective. ZNF143 is an inducible gene by other DNA damaging agents such as gamma-irradiation, etoposide and adriamycin. ZNF 143 also binds preferentially to cisplatin-modified DNA. These results suggest that ZNF 143 participates in cellular responses to DNA damage.

ZFPs (Zinc Finger Proteins) play important roles in various cellular functions, including transcriptional activation, transcriptional repression, cell proliferation, and development. C(2)H(2) (Cys-Cys-His-His motif) ZFPs are the most abundant proteins among the founding members of the ZFP super family in eukaryotes. In this study, we isolate a novel C(2)H(2) ZNF (Zinc Finger) gene ZNFD. It contains an ORF (Open Reading Frame) with a length of 990 bp, encoding 329 amino acids. The predicted protein contains a C(2)H(2) zinc finger. RT-PCR analysis in 18 human adult tissues indicated that it was expressed in five human adult tissues. Green fluorescence protein localization analysis showed that human ZNFD was located in the nucleus of Hela cells. Overexpression of ZNFD in the COS7 cells activates the transcriptional activities of AP1(PMA) (Activator of protein 1, that responds specifically to phorbol ester). Together the data indicate that ZNFD is probably a new type of C(2)H(2) ZFP and the ZNFD protein may act as a transcriptional activator in PKC (protein kinase C) signal pathway to mediate cellular functions.
