Zinc finger proteins are a type of protein that can bind to DNA, RNA, or other proteins. They are characterized by their unique structure, which includes small, finger-like loops stabilized by zinc ions. This structure allows them to interact specifically with certain sequences of DNA, playing a crucial role in gene regulation and expression. These proteins are involved in various biological processes, including cell differentiation, development, and immune response. Due to their ability to target specific genes, zinc finger proteins are also being explored for use in gene therapy and biotechnology, offering potential applications in treating genetic disorders.
