ZC3H11 activity requires the interactions with MKT1 and PBP1. The diagrams on the left illustrate selected mutant versions of ZC3H11. Zn: zinc finger; PY: HNPY motif; S: serine-rich domain. Properties of the mutants are shown in the columns. Only selected, critical, mutants are shown. Bind RNA: ability to bind (UAU) repeats (26). Y2H MKT1: binding to MKT1 in the yeast two-hybrid assay. Y2H PBP1: binding to PBP1 in the yeast two-hybrid assay; Tether effect: ability to increase CAT activity and CAT mRNA in the tethering assay. + , positive result; –, negative result; gap, not done.
