BACKGROUND Recent studies on the involvement of the G12 family of heterotrimeric G proteins (Gα12 and Gα13, the products of the GNA12 and GNA13 genes, respectively) in oncogenic pathways have uncovered a link between G12 signaling and cancer progression. However, despite a well characterized role of Rho GTPases, the potential role of secreted factors in the capacity of G12 signaling to promote ...

Keratinase is an important industrial enzyme, but its application performance limited by low activity. A rational design of 5′-UTRs that increases translation efficiency approach to enhance protein expression. Herein, we optimized the 5′-UTR recombinant keratinase KerZ1 expression element secretory activity in Bacillus subtilis WB600 through Spacer design, RBS screening, and sequence simplifica...
