Deletion of the P6.1 stem–loop abrogates association of CR4/5–60 with RNA33–147. (A) 32P 5′-end labeled deltaP6.1 in the presence of excess unlabeled RNA. (B) 32P 5′-end labeled RNA33–147 in the presence of excess unlabeled RNA. The data show that no band shift is observed when the P6.1 hairpin is deleted from the CR4/CR5 domain.
