Provided herein are methods and compositions for the in vitro formation of multi subunit biological platforms. The biological platforms may be used to screen chemical or biological compounds, in particular compounds that may disrupt or otherwise affect the formation of the multi subunit complexes, or disrupt already-formed in vitro assembled multi subunit complexes. Also provided herein are methods and compositions for the in vivo formation of multi-subunit biological complexes. The methods and compositions described herein may be used to develop animal models of diseases or disorders.
