Cbf11 and Cbf12 proteins, the members of the CSL transcription factors family, are involved in a wide range of cellular processes in the fission yeast Schizosaccharomyces pombe - among other things they regulate cell adhesion and they have also been implicated in maintenance of genome integrity. At the level of the whole genome we previously identified target loci bound by CSL proteins in vivo. Many of them do not contain any consensus CSL-binding element. There are probably different DNA binding modes of the Cbf11/12 proteins and it has not been known what specific biological function is associated with the particular way of DNA binding. For the purpose of studying CSL DNA binding modes we have worked in this project on the implementation of the DNA binding mutation (DBM), which prevents direct DNA binding of CSL proteins to canonical motif in vitro, into the chromosomal locus of the cbf11 and cbf12 genes. Using the "ura4 selection system" we have successfully constructed the scar-less Cbf12-TAP and Cbf12DBM-TAP knock-ins, i.e. the strains without/with DBM in the open reading frame of Cbf12 where Cbf12 is C- terminally TAP-tagged and contains the intact 3'UTR. In our laboratory we have established the CRISPR/Cas9 system by which we have been able to prepare the Cbf11- TAP strain. We have failed to...
