(D) EMSA showing that Zar1 directly binds to the TCSs in the Wee1 UTR
(D) EMSA showing that Zar1 directly binds to the TCSs in the Wee1 UTR. RNA than Zar2. To show the functional significance of the conserved amino acid substitutions, these residues in Zar2 were mutated to those found in Zar1. We show that these residues contributed to the different RNA binding characteristics of Zar1 compared to…
