Ets transcription factors are a family of proteins that play a crucial role in regulating gene expression. They bind to specific DNA sequences, influencing the transcription of target genes involved in various biological processes, including cell growth, differentiation, and apoptosis. These factors are characterized by a conserved Ets DNA-binding domain, which allows them to recognize and attach to specific regions of DNA. Ets transcription factors are important in development and have been implicated in various diseases, including cancer, due to their role in controlling cell behavior and signaling pathways.
