Synthetic promoters are particularly relevant for application not only in yeast expression systems designed for high-level heterologous protein production but also in other applications such as metabolic engineering, cell biological research, and stage-specific gene expression control. By designing synthetic promoters, researcher can create customized expression systems tailored to specific needs, whether it is maximizing protein production or precisely controlling gene expression at different stages of a process. While recognizing the limitations of endogenous promoters, they also provide important information needed to design synthetic promoters. In this review, emphasis will be placed on some key approaches to identify endogenous, and to generate synthetic promoters in yeast expression systems. It shows the connection between endogenous and synthetic promoters, highlighting how their interplay contributes to promoter development. Furthermore, this review illustrates recent developments in biotechnological advancements and discusses how this field will evolve in order to develop custom-made promoters for diverse applications. This review offers detailed information, explores the transition from endogenous to synthetic promoters, and presents valuable perspectives on the next generation of promoter design strategies.
