What is Green Fluorescent Protein (GFP) originally derived from?

Green Fluorescent Protein (GFP) is originally derived from the jellyfish Aequorea victoria. This marine organism is known for its bioluminescent properties, which are a result of the protein's unique ability to fluoresce green when exposed to ultraviolet or blue light. The discovery of GFP in Aequorea victoria opened doors for its use in molecular and cellular biology as a fluorescent marker, allowing scientists to visualize and track proteins, cells, and even whole organisms in biological research. The properties of GFP, including its stability and brightness, have made it an invaluable tool in a variety of applications, including gene expression studies, protein localization, and even live-cell imaging. This foundational knowledge about its origin is critical for understanding its application and significance in scientific research.
