Stability of the coding genome and signaling within the active genome

We have shown that the essential chromosomal kinase JIL-1 forms a stable epigenetic “reader-writer” module with JASPer, which targets the complex to transcribed genes (Albig et al., 2019). The Complex is however not essential for transcription. Our current model is that distribution of the kinase complex genome-wide is important for genome stability at various levels: maintenance of telomers, balance between euchromatin and constitutive heterochromatin and stability of the coding genome in particular. The project aims to elucidate, which specific (stress) signals activate JIL-1 kinase and what are the substrates of JIL-1 besides histone H3. We will concentrate on endogenous sources of DNA damage linked to transcription (e.g. R-loop formation). The JIL-1-dependent phospho-proteome hits will be considered (1) for their potential role in genome stability, (2) for their (conditional) association to the complex interaction network of JIL-1 and/or JASPer, (3) their genome-wide distribution.

*SLiM: Small Linear conserved Motif (FxGF) bound by the LEDGF domain of JASPer. KD: Kinase domain, KDII activates KDI, which then phosphorylates substrates. PEST motifs are found in unstable proteins: JIL-1 is degraded in the absence of JASPer. PWWP domain of JASPer is a reader domain binding nucleosomes with histone H3K36me3
