Spt proteins are defined as a large family of transcription regulators of the yeast Saccharomyces cerevisiae. They are crucial components of the SAGA complex that regulates transcription through interaction with the TATA box in the upstream region of the target genes. About 10% of total gene transcriptions are related to Spt proteins and these genes are highly related to environmental stress response. Such vast regulation network and complex mechanisms have become a hotspot. Spt proteins are also important to suppress transposon-induced mutations, being a switch on regulation of transposon behaviors and adaptive evolution of Saccharomyces cerevisiae. Besides that, some Spt proteins are directly involved in regulating unsaturated lipid acids synthesis, which could remold the cell membrane to resist environmental stresses. Here, we review Spt proteins, the advances in Spt proteins study, and their potential applications in improving yeast's stress resistance through transcription regulation, transposon activity regulation and cell membrane alternation.
