Abstract

Transcription is a fundamental process that is tightly regulated by transcription factors to maintain cellular homeostasis. Transcription factors have DNA-binding domains, some of which are sequence specific, and are found throughout the eukaryotic kingdom. Recent studies have revealed the molecular mechanisms by which transcription factors perform their functions. In the budding yeast Saccharomyces cerevisiae, Rap1 (ScRap1) can either activate or repress transcription. This bimodal transcriptional activity has led to the widespread study of the mode of action of ScRap1. This review summarizes current knowledge about yeast ScRap1, including its structure, mechanisms of transcription regulation, and biological functions, and the future directions in the field.
