"Calling cards" for DNA-binding proteins in mammalian cells.
The ability to chronicle transcription-factor binding events throughout the development of an organism would facilitate mapping of transcriptional networks that control cell-fate decisions. We describe a method for permanently recording protein-DNA interactions in mammalian cells. We endow transcription factors with the ability to deposit a transposon into the genome near to where they bind. Th...
متن کاملCalling cards for DNA-binding proteins.
Identifying genomic targets of transcription factors is fundamental for understanding transcriptional regulatory networks. Current technology enables identification of all targets of a single transcription factor, but there is no realistic way to achieve the converse: identification of all proteins that bind to a promoter of interest. We have developed a method that promises to fill this void. ...
متن کاملCalling Cards enable multiplexed identification of the genomic targets of DNA-binding proteins.
Transcription factors direct gene expression, so there is much interest in mapping their genome-wide binding locations. Current methods do not allow for the multiplexed analysis of TF binding, and this limits their throughput. We describe a novel method for determining the genomic target genes of multiple transcription factors simultaneously. DNA-binding proteins are endowed with the ability to...
متن کاملSingle stranded DNA binding proteins derive from hnRNP proteins by proteolysis in mammalian cells.
As we have previously demonstrated, mammalian single stranded DNA binding proteins (ssDBP) and heterogeneous nuclear RNA binding proteins (hnRNP proteins) are antigenically and structurally related. In this paper we show that ssDBP are specific proteolytic products of hnRNP core proteins. Proteolysis can be observed in crude extract, both total and nuclear and is not inhibited by the most commo...
متن کاملTopic Introduction Transposon Calling Cards
Identifying the genomic targets of transcription factors is an important step in understanding the regulatory networks of gene transcription in yeast. We have developed a method that utilizes what we refer to as transposon “calling cards,” in which a transcription factor directs the Ty5 retrotransposase to insert transposons into the genome adjacent to where the transcription factor binds. This...
