摘要:
The invention provides criteria and methods for selecting optimum subsequence(s) from a target gene for targeting by a zinc finger protein. Some of the methods of target site selection seek to identify one or more target segments having a DNA motif containing one or more so-called D-able subsites having the sequence 5′NNGK3′. Other methods of the invention are directed to selection of target segments within target genes using a correspondence regime between different triplets of three bases and the three possible positions of a triplet within a nine-base site. In another aspect, the invention provides methods of designing zinc finger proteins that bind to a preselected target site. These methods can be used following the preselection of target sites according to the procedures and criteria described above. The methods of design use a database containing information about previously characterized zinc finger proteins.
摘要:
The present disclosure provides methods and compositions for identifying a particular genomic sequence as a gene and/or a coding region, once that sequence has been tentatively identified as a gene based on genomic analysis using one or more gene prediction algorithms. The methods include the use of exogenous molecules such as zinc finger proteins which are capable of binding to and modulating expression of gene transcription, targeted to putative gene sequences, followed by assay for one or more selected phenotypes.
摘要:
The invention provided for a method of transcriptionally modulating the expression of a gene encoding a protein of interest associated with treatment of one or more symptoms of a cardiovascular disease. Further provided is a method of determining whether a molecule not previously known to be a modulator of protein biosynthesis is capable of directly and specifically transcriptionally modulating the expression of a gene encoding a protein of interest associated with treatment of one or more symptoms of a cardiovascular disease. Screening methods, including methods of essentially simultaneously screening molecules to determine whether the molecules are capable of directly and specifically transcriptionally modulating one or more genes encoding proteins of interest associated with treatment of one or more symptoms of a cardiovascular disease, are also provided.

The present invention relates to methods of using libraries of randomized zinc finger proteins to identify genes associated with selected phenotypes.
摘要:
The present invention provides a method of transcriptionally modulating the expression of a gene encoding a protein of interest, the expression of which gene is associated with the production in cell culture of a protein encoded by the gene, which comprises contacting a cell, which is capable of expressing the gene, with an amount of a molecule effective to transcriptionally modulate expression of the gene and thereby affect the level of the protein encoded by the gene which is expressed by the cell in culture, which molecule (a) directly transcriptionally modulates expression of the gene.
