Part:BBa_K2520008
CMV-Tri display-hGH
This device is a complete system for displaying proteins on cells' membrane. We combined three independent systems into one, which allows for the expression of three unique proteins. The Igk leader (BBa_K2520024,BBa_K2520028,BBa_K2520029) is a short signal peptide that prompts the translocation of a protein to the cellular membrane. PDGFR (BBa_K2520026,BBa_K2520036,BBa_K2520037) is a trans-membrane domain that anchors all the components located between the igk leader and the PDGFR itself to the membrane. HA (BBa_K2520030), Myc (BBa_K2520031) and His (BBa_K2520032) are tags that bind to specific antibodies and provide an indirect method for verifying the display of the proteins on the membrane. The proteins that we chose to express on the membrane are three epitopes that are known targets of multiple sclerosis (BBa_K2520038,BBa_K2520039,BBa_K2520040) and are components related to our specific project. P2A (BBa_K2520033) and T2A (BBa_K2520034) are internal peptide cleavage sites that allow for the equimolar expression of multiple proteins under the same promoter.
The CMV promoter (BBa_K1119006) is a constitutive expression promoter in mammalian cells and hGH (BBa_K404108) serves as a terminator. The structure of this device is shown below.
