TAL Effector DNA-Binding Principles and Specificity

WebThe interaction of TALEs and host genes can be characterized as protein/DNA interaction, i.e., TALEs, once internalized into nuclei of host cells, recognize the promoters and transcriptionally activate the disease susceptibility genes, inducing a state of disease. WebTALE fusion proteins use the C-terminal region downstream of CRD as a linker between TALE DBD and the effector domain. The optimal length of the linker may vary for different effector domains, e.g. a short 17–65 aa linker is used for the dimerizing FokI nuclease domain [ 13 , 28 ], whereas a longer linker (∼65 aa) was used for activation domains [ 14 , …
