We subsequent investigated regardless of whether the two domains of Rpl22 could differentially contribWe next investigated whether or not the two domains of Rpl22 could differentially contribute to the the observed DNA rotein interaction. The H1-H5 domain and ribosomal domain ute to observed DNA rotein interaction. The H1-H5 domain and the the ribosomal dowere independently tested in EMSA assays for their ability to interact with Doc5. As key have been independently tested in EMSA assays for their capability to interact withDoc5. As might be observed in Figure four, only the H1-H5 domain retains the capability to bind the Doc5 can be observed in Figure 4, only the H1-H5 domain retains the ability to bind the Doc5 fragment tested (Figure 4, lane three), whereas the ribosomal domain will not (Figure lane two) fragment tested (Figure 4, lane 3), whereas the ribosomal domain does not (Figure four, 4, lane if compared to the binding observed for the COX Activator manufacturer wild-type Rpl22 protein (Figure 4, lane 4). 2) if in comparison to the binding observedfor the wild-type Rpl22 protein (Figure four, lane four).
