Overview of mammalian circuit assembly (mMoClo). (A) mMoClo is based on a library of empty backbones used to assemble parts (Parts Positioning Vectors), transcription units (Transcription Unit Positioning Vectors) and complex multi-unit circuits (Destination Vector) to be integrated into the landing pad. The Parts Library is made of sequence-verified basic genetic parts (Insulators, Promoters, 5′ UTR, Genes, 3′UTR and polyA sequences). (B) One-step creation of an integration vector carrying BxB1 attB site and promoterless selection marker. (C) One-step assembly of different functional transcription units in specific position vectors. (D) One-step assembly of a multi-unit genetic circuit by combining the desired transcription units, the corresponding linker vector and the previously built integration vector carrying the promoter-trap cassette. Details of the overhangs used in the assembly process are provided in Supplementary Figure S4.
