Abstract: A family of p53 tumor suppressor nucleic acid and protein isolated from several insect species is described. The p53 nucleic acid and protein can be used to genetically modify metazoan invertebrate organisms, such as insects and worms, or cultured cells, resulting in p53 expression or mis-expression. The genetically modified organisms or cells can be used in screening assays to identify candidate compounds that are potential pesticidal agents or therapeutics that interact with p53 protein. They can also be used in methods for studying p53 activity and identifying other genes that modulate the function of, or interact with, the p53 gene. Nucleic acid and protein sequences for Drosophila p33 and Rb tumor suppressors are also described.

Abstract: The present invention relates to C. elegans insulin-like genes and methods for identifying insulin-like genes. The methods provide nucleotide sequences of C. elegans insulin-like genes, amino acid sequences of their encoded proteins, and derivatives (e.g., fragments) and analogs thereof. The invention further relates to fragments (and derivatives and analogs thereof) of insulin-like proteins which comprise one or more domains of an insulin-like protein. Antibodies to an insulin-like protein, and derivatives and analogs thereof, are provided. Methods of production of an insulin-like protein (e.g., by recombinant means), and derivatives and analogs thereof, are provided. Further, methods to identify the biological function of a C. elegans insulin-like gene are provided, including various methods for the functional modification (e.g., overexpression, underexpression, mutation, knock-out) of one or more genes simultaneously. Still further, methods to identify a C.

Abstract: Tandem pore domain weak inward rectifying K+ (TWIK) channel nucleic acids and proteins that have been isolated from Drosophila melanogaster and Leptinotarsa are described. The TWIK channel nucleic acids and proteins can be used to genetically modify metazoan invertebrate organisms, such as insects, coelomates, and pseudocoelomates, or cultured cells, resulting in TWIK channel expression or mis-expression. The genetically modified organisms or cells can be used in screening assays to identify candidate compounds which are potential pesticidal agents or therapeutics that interact with TWIK channel proteins. They can also be used in methods for studying TWIK channel activity and identifying other genes that modulate the function of, or interact with, the TWIK channel gene.
