This project will investigate the molecular mechanisms and physiological consequences of chromatin recruitment of the serine/threonine kinase HIPK2 . We have already performed ChIP-Seq experiments and found that HIPK2 binding motifs have a prominent overlap with DNA motifs for a zinc finger transcription factor, suggesting that this transcription factor functions as a docking port for the kinase. It is thus planned to measure chromatin association of HIPK2 or the transcription factor after shRNA-mediated depletion of the respective interaction partner. It will also be important to determine the effects of transcription factor and/or HIPK2 depletion on mRNA expression of their target genes by RT-qPCR. The transcription factor and HIPK2 share a number of common binding partners, therefore it will be interesting to reveal whether these partners also occur at the genomic loci containing the transcription factor/HIPK2 complex. In addition we will use the CRISPR-Cas system to remo!
ve prototypic genomic HIPK2/transcription factor binding sites, followed by the analysis of HIPK2 and transcription factor chromatin recruitment by ChIP experiments. A variety of different methods will be employed to understand the mechanisms and physiological consequences of HIPK2 chromatin recruitment.
