Chromatin immunoprecipitation analysis of Phospho-c-Abl (pTyr89) was performed using cross-linked chromatin from 1x10^6 HCT116 colon carcinoma cells treated with serum for 0, 15, 30, and 60 minutes. Immunoprecipitation was performed using a multiplex microplate Matrix ChIP assay (see reference for Matrix ChIP protocol: http://www.ncbi.nlm.nih.gov/pubmed/22098709) with 1.0ul/100ul well volume of a Phospho-c-Abl (pTyr89) monoclonal antibody (Product # MA5-14796). Chromatin aliquots from ~1 x 105 cells were used per ChIP pull-down. Quantitative PCR data were done in quadruplicate using 1ul of eluted DNA in 2ul SYBR real-time PCR reactions containing primers to amplify exon 3-3 of human Bcl-x (hBcl-x) or exon 1 of human NR4A3 (hNR4A3). PCR calibration curves were generated for each primer pair from a dilution series of sheared total genomic DNA. Quantitation of immunoprecipitated chromatin is presented as signal relative to the total amount of input chromatin. Results represent the mean +/- SEM for three experiments. Schematic representations of the Bcl-x and NR4A3 loci are shown above the data where boxes represent exons (black boxes = translated regions, white boxes = untranslated regions). Regions amplified by Bcl-x and NR4A3 primers are represented by black bars. Data courtesy of the Innovators Program.

The ABL1 protooncogene encodes a cytoplasmic and nuclear protein tyrosine kinase that has been implicated in processes of cell differentiation, cell division, cell adhesion, and stress response. Activity of c-Abl protein is negatively regulated by its SH3 domain, and deletion of the SH3 domain turns ABL1 into an oncogene. The t(9;22) translocation results in the head-to-tail fusion of the BCR and ABL1 genes present in many cases of chronic myelogeneous leukemia. The DNA-binding activity of the ubiquitously expressed ABL1 tyrosine kinase is regulated by CDC2-mediated phosphorylation, suggesting a cell cycle function for ABL1. The ABL1 gene is expressed as either a 6- or 7-kb mRNA transcript, with alternatively spliced first exons spliced to the common exons 2-11.
