E. Results of the phospho-Y2H screen to identify kinases modulating the interaction of AAR2 and PRP8. Growth on selective media (SD5), of strains carrying AAR2 bait and PRP8 prey plasmids is reduced through co-expression of either SGK2 or CK2α1(CSNK2A1). Growth reduction is visible in a 1:10 dilution series on selective agar (SD5) in comparison to the control media (SD3). Ctrl: non-related kinases.
