Zinc Finger Proteins Review - EpiGenie

Zinc finger (ZnF) proteins are a massive, diverse family of proteins that serve a wide variety of biological functions. Due to their diversity, it is difficult to come up with a simple definition of what unites all ZnF proteins; however, the most common approach is to define them as all small, functional domains that require coordination by at least one zinc ion (Laity et al., 2001).
