Why is my recombinant construct failed to restore the same gene expression level as of endogenous protein?

I synthesised pAdenovirus expressing Protein-FLAG tagged and reconstituted in knockdown cells. When I perform the experiment, WT cells can perform the gene expression but reconstituted cells can...

I want to prepare an overexpression module for my protein with a N-ter HA tag. Can you suggest me the possible strategies?

I have tried by breaking the protein into multiple fragment and using the PCR products to clone one by one. I successfully cloned into the pShuttle vector but I couldnt get the expressed protein,...
