Heterochromatin Protein Activates the Amylase Expression Pathway and Its Application to Recombinant Protein Expression in Penicillium oxalicum.

Remodelling regulatory pathways to directionally increase the efficiency of specific promoters in chassis cells is an effective strategy for the rational construction of expression systems. However, the repeated utilization of one regulator to modify the host cell to improve expression motif efficiency has a limited effect. Therefore, it is preferable to identify new regulatory factors to activate specific pathways and thus further improve the efficiency of target elements.
