Abstract
Provided is a modular construction of synthetic gene circuits in mammalian cells using TALE transcriptional repressors. Provided is a method for achieving regulated expression of two proteins: an expression cassette A comprises a feedback element coding sequence, a promoter A, a protein A and TALER protein A encoding gene linked by means of a self-cleaving polypeptide, and a target sequence A (comprising an shRNA1 target sequence); an expression cassette B comprises a feedback element coding sequence, a promoter B, a protein B and TALER protein B encoding gene linked by means of a self-cleaving polypeptide, and a target sequence B (comprising an shRNA2 target sequence); an expression cassette C comprises a constitutive promoter and an activating element-coding sequence; a recombinant vector A having the expression cassette A, a recombinant vector B having the expression cassette B, and a recombinant vector C having the expression cassette C are introduced into host cells to regulate the expression of protein A and protein B by adding shRNA1 or shRNA2.
