Parts Overview
This year, we handed in 44 high-quality, well documented bio-brick parts, including all those we used in our project this year, and several brilliantly designed others forming a inspired by our iGEM project within these three years.
2.1 Basic Part: αCHelix of truncated CDK4 (BBa_K4016009)
This part is a basic part, the αCHelix domain of CDK4. CDK4 is known as endogenous binding parter of Cyclin D1. Reports have shown that CDK4 binds Cyclin D1 via its C terminus α Helix domain1. Therefore, we removed other protein domains of cyclin D1 to only obtain the binding afinity. In addition, to improve binding affinity, our part contains two copies of CDK4 αCHelix linked with 5xGS Linker.

2.2 Composite Part: 2x CDK4 αCHelix-CIB1 (BBa_K4016027)
This part is a composite part containing tendom repeats of CDK4 αCHelix(BBa_K4016009) linked with CIB1(BBa_K2980002) designed for the usage of degrading cyclinD1 and then the regulation of the cell cycle under blue light. By keeping the C-terminal helix of CDK4, we can get the part that only targets cyclinD1. Meanwhile, with the “CIB1” part, we can achieve the degradation of protein controlled by the blue light by working with composite part “Trim21-Cry2” (BBa_K4016035).
