C-terminal domain

The C-terminal domain is a specific part of a protein located at its tail end, called the "C-terminus." Proteins are made of long chains of building blocks (amino acids), and the C-terminal domain is a region near the end of this chain that often plays a key role in how the protein functions. It can determine where the protein goes in the cell, how it interacts with other molecules, or how it performs its specific task. Think of it as the protein’s "tail," critical for its proper operation and interactions.
