Supplementary info

- Activity summary
GAL4 also known as a transcription factor is an important protein in yeast. It plays a critical role in regulating the transcription of genes involved in galactose metabolism. The GAL4 protein has a mass of approximately 881 amino acids and is mainly expressed in the nucleus of yeast cells. Common parts of GAL4 include the GAL4 DBD (DNA-binding domain) and GAL4 AD (activation domain) which are critical for its function. Although similar sounding GAL4 should not be confused with galectin-4 or galectin 4 which are different proteins.
- Biological function summary
The GAL4 transcription factor functions as a major regulator of galactose-responsive genes. It acts as part of a complex binding with its DNA target sites to initiate transcription of GAL genes like GAL1 GAL7 and GAL10. GAL4 protein recruits transcriptional machinery through its activation domain working alongside other factors to turn on specific gene expression in response to the presence of galactose. This capacity for gene regulation underlines its essential role in sugar metabolism in yeast.
- Pathways
GAL4 is intimately involved in the GAL gene regulatory pathway that manages the cellular response to galactose. In this pathway proteins such as GAL80 inhibit GAL4 function under non-inducing conditions. However in the presence of galactose GAL3 binds and neutralizes GAL80 liberating GAL4 to activate gene expression. This system exemplifies a dynamic interaction in yeast allowing precise gene regulation in accordance with sugar availability.
- Associated diseases and disorders
While GAL4 is specifically a yeast protein and does not directly relate to human diseases its functional analogs and concepts have implications in genetic research and synthetic biology. For example GAL4 system is widely used in Drosophila and other model organisms to study gene expression patterns and related disorders. This system compared with mammalian transcription factors provides a foundational methodology for exploring genetic regulation mechanisms and potential implications in understanding metabolic disorders.
