Question in lab experiment

[ChengkuiZhao]

Recently, I am doing work on denovo design protein based on publication -"RFdiffusion". In the protein design part, I have one question, could you please help me? In the design of expression vectors, the "MSG - [protein]-GSGSHHWGSTHHHHHHH vector construction method is used.". I would like to inquire about the functions of MSG gene elements and whether there is corresponding sequence information that can be provided? Thank you for your patience and wait for your reply.
