Self-protein
Self-protein
Self-protein (pronunciation: /sɛlf 'proʊti:n/) is a type of protein that is produced by an organism's own cells.
Etymology
The term "self-protein" is derived from the English words "self", meaning one's own person, and "protein", a complex organic compound.
Definition
A self-protein is a protein that is produced by an organism's own cells. These proteins are recognized as "self" by the immune system, which means they are not targeted for destruction. This is in contrast to "non-self" proteins, which are foreign to the body and are targeted by the immune system for destruction.
