Part:BBa_K1861303

Designed by: Vladyslav Vyshnevskyi   Group: iGEM15_FAU_Erlangen   (2015-09-18)

CMV Promoter

Human cytomegalovirus (CMV) promoter without enhancer. The sequence includes the binding sites for TALE1 BBa_K1861501 and TALE2 BBa_K1861601.
This part has not been created as a standalone. Instead, it is a component of BBa_K1861030.

Literature Characterization by AFCM-Egypt 2022 team

An essential part originated from the human cytomegalovirus we employ it to regulate the expression of the Cas12g the protein domain of our CRISPR regulatory system CMV promoter is known to have a moderate level of expression lesser than other promoters we take advantage of that to limit the possibility of overexpression of Cas12g to reduce the off targeting effect

Figure.2 Effect of different promoter on transfection efficiency and transient transgene expression using eGFP antibody analysis.



The greatest expression levels were seen in the cells transfected with CHEF-1 promoter-carrying vectors, followed by those with HEF-1, CMV mutant, CMV, mouse CMV, CAG, CAG enhancer, and PGK. When the amount of eGFP expression under the CMV promoter was taken into account as 100, the levels of eGFP expression under the PGK, CHEF-1, HEF-1, mouse CMV, CMV mutant, CAG, and CAG enhancer promoters were 218.13, 184.21, 164.33, 49.12, 47.95, and 8.77, respectively.
