The potentially responsible parties (PRPs) have removed the beaver dams and have collected the sediment samples they need for treatability studies. The treatability studies will establish the correct silt fence to minimize releases of sediment during the actual dredging to occur this fall. The studies will also determine the types and amounts of materials (lime, kiln dust, fly ash, etc.) required to stabilize the sediment, chemically tie up the metals and insure the sediment mixture will bear the weight of the cap on the Interim Storage Cell where the sediment will be placed. The Illinois Environmental Protection Agency (Illinois EPA) anticipates work to be completed by late fall or early winter 2004, if lake and river levels that affect the South Ditch are at their normal seasonal levels.

Zinc-finger-containing proteins can be classified into evolutionary and functionally divergent protein families that share one or more domains in which a zinc ion is tetrahedrally coordinated by cysteines and histidines. The zinc finger domain defines one of the largest protein superfamilies in mammalian genomes; 46 different conserved zinc finger domains are listed in InterPro (http://www.ebi.ac.uk/InterPro). Zinc finger proteins can bind to DNA, RNA, other proteins, or lipids as a modular domain in combination with other conserved structures. Owing to this combinatorial diversity, different members of zinc finger superfamilies contribute to many distinct cellular processes, including transcriptional regulation, mRNA stability and processing, and protein turnover. Accordingly, mutations of zinc finger genes lead to aberrations in a broad spectrum of biological processes such as development, differentiation, apoptosis, and immunological responses. This study provides the first comprehensive classification of zinc finger proteins in a mammalian transcriptome. Specific detailed analysis of the SP/Kruppel-like factors and the E3 ubiquitin-ligase RING-H2 families illustrates the importance of such an analysis for a more comprehensive functional classification of large protein families. We describe the characterization of a new family of C2H2 zinc-finger-containing proteins and a new conserved domain characteristic of this family, the identification and characterization of Sp8, a new member of the Sp family of transcriptional regulators, and the identification of five new RING-H2 proteins.
