PP2CA-TTADH1-pCyc

It is one of the Basic Part in the eukaryotic version of signal filter (BBa_K2036030)and it is constructed by In-Fusion method.

Protein expression

Pichia pastoris are typical Eukaryotic expression host, but expressing plant genes are still a big challenge. So we firstly tested whether our three interest genes can be efficient expressed. We measured the secretion expression of PP2CA, ABF2 and SnRK2.2. We ran a SDS-PAGE of the culture supernatants of induced cells to identify the three recombinant proteins (Fig1). Compared to vector trasnfected cells, 3 kinds of recombinant protein plasmids trasnfected cells all expressed proteins at ~80kD under induction. The shift of protein bands suggested potential glycosylation modification.

Bi-stable function:

We constructed expression plasmid and submitted this part (BBa_K2036030) to the registry. But due to the limited time, its function characterization is still under testing. However, our modeling simulation showed promising switch functions. ([http://2016.igem.org/Team:HUST-China/Model/model-euk See more details in our Eukaryote circuit modeling]).
