The White Lab is aiming to map the association of all the Drosophila Transcription Factors (TF) and DNA associated proteins on the fly's whole genome. The main technique that will be used for this purpose is ChIP-chip. To achieve this goal, we designed a multi-step pipeline starting from the comprehensive listing of the fly TF to the classification of cis-regulatory modules (CRM). The steps of this pipeline are described in the figure below. The Module 1 aims to produce ChIP-grade antibodies for every TF in the fly genome. After thorough validation these antibodies will be used for the ChIP experiments performed in the Module 2. The ChIP samples produced will then be used to hybridize whole-genome tiling microarays. The data generated by ChIP-chip experiments consist basically of a plot of signal intensity across the genome. The highest signals correspond to positions in the genome occupied by the tested TF. The Module 3 aims to identify these binding sites, to classify them and to extract biological information by extensive comparaison between the different datasets. Also developed in the computational part of the pipeline is a tracking database called DSTN to help in coordination of the different persons involved in the pipeline.
The details and persons involved in every step of this pipeline are summarized below.
