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.

Zinc finger proteins (ZFPs) that contain multiple cysteine and/or histidine residues perform important roles in various cellular functions, including transcriptional regulation, cell proliferation, differentiation, and apoptosis. The Cys-Cys-His-His (C(2)H(2)) type of ZFPs are the well-defined members of this super family and are the largest and most complex proteins in eukaryotic genomes. In this study, we identified a novel C(2)H(2) type of zinc finger gene ZNFD from mice which has a 1,002 bp open reading frame and encodes a protein with 333 amino acid residues. The predicted 37.4 kDa protein contains a C(2)H(2) zinc finger domain. ZNFD gene is located on chromosome 18qD1. RT-PCR analysis revealed that the ZNFD gene was specifically expressed in mouse testis but not in other tissues. Subcellular localization analysis demonstrated that ZNFD was localized in the nucleus. Reporter gene assays showed that overexpression of ZNFD in the COS7 cells activates the transcriptional activities of heat shock element (HSE). Overall, these results suggest that ZNFD is a member of the zinc finger transcription factor family and it participates in the transcriptional regulation of HSE. Many heat shock proteins regulated by HSE are involved in testicular development. Therefore, our results suggest that ZNFD may probably participate in the development of mouse testis and function as a transcription activator in HSE-mediated gene expression and signaling pathways.
