Family of proteins

A family of proteins is a group of proteins that share similar structures and functions because they come from a common ancestor gene. Think of them as relatives in a large gene "family," with similar building blocks that have evolved to perform related roles in the body. These proteins often have comparable shapes and mechanisms, allowing them to work together or adapt to different functions while maintaining a shared origin. Recognizing families of proteins helps scientists understand how they evolved and how they carry out essential processes in the body.
