Genome-wide maps of chromatin state in Ba/F3 cell with PAX5-KIDINS220 fusion protein

ABSTRACT: PAX5-KIDINS220 (PAX5-K220) is a novel chimeric fusion gene identified in a pediatric Philadelphia chromosome (Ph)-like acute lymphoblastic leukemia (ALL) patient, but the function of the encoded fusion protein has not yet been analyzed. Here, using in vitro murine assays and ChIP-sequencing, we demonstrate that PAX5-K220 is a nuclear protein that inhibits PAX5 transcriptional activity in a dominant-negative fashion, resulting in a B-cell differentiation block. Gene expression analysis and ChIP-sequencing revealed that PAX5-K220 is associated with multiple pathways related to chemotaxis and migration.
