Definition
Proteins that influence gene expression by binding to regulatory DNA sequences.
Summary
Regulatory proteins play a crucial role in the process of transcription, which is the first step in gene expression. These proteins, including transcription factors, enhancers, and silencers, interact with DNA to either promote or inhibit the transcription of specific genes. Understanding how these proteins function is essential for grasping the complexities of gene regulation and expression. In the field of molecular biology, the study of regulatory proteins has significant implications for biotechnology and medicine. By manipulating these proteins, scientists can develop innovative therapies for genetic disorders and cancer. This knowledge not only enhances our understanding of cellular processes but also opens doors for advancements in genetic engineering and therapeutic interventions.
