Overall project
This year, our project named "Cell Magic" we engineered the budding yeast in time level as well as space level. The "Cell Magic", like a movie,can be divided into two parts: the actor related and the time regulation related one. In the first part, our actor, signal peptides, were all made up with colorful clothes by the fluorescent proteins. Furthermore, the intron and degradation biobricks as make-up artists can decide how the clothes be matched. Through these steps, our actors may wearing in green, yellow or even mixed, appear in their specific sub-locations of yeast cell. With respect to the time level, we took advantages of the natural cell cycle in budding yeast to improve the time process to be more suitable for our movie.In general, the movie director, the promoters from five cycline gene, can decide the expression of downstream gene in G1 and G2 phase phase, respectively. Also, freezer Sic1 help our movie stay a longer time in the G1 phase which is important for the actor performing their stories. And the last tools we utilized is the microfluidics, through which numerous cells can project our "Cell Magic", thus ensuring our observation by naked eyes.
Project Details
Actor - signal peptides
A target peptide is a short (3-70 amino acids long) peptide chain that directs the transport of a protein to a specific region in cell, including nucleus, mitochondria, endoplasmic reticulums (ERs), chloroplasts, apoplasts, peroxisomes and plasma membrane. Targeting peptide can exists in both N-terminal, C-terminal and internal sequence of a precursor protein. And after transported, some target peptides are cleaved by signal peptidases. In our project we utilized 19 peptides target to 9 sub-locations in yeast cells, and when combined with fluorescent proteins, such region can be marked by different colors.
