S100 Family
The S100 family refers to a group of proteins characterized by their ability to bind calcium and zinc ions. These proteins play crucial roles in various cellular processes, including cell growth, differentiation, and apoptosis. They are primarily found in the nervous system and immune system, where they help regulate inflammation and neuronal function.
Members of the S100 family are often used as biomarkers in medical research, particularly in cancer and neurodegenerative diseases. Their expression levels can provide insights into disease progression and potential therapeutic targets. Overall, the S100 proteins are essential for maintaining cellular homeostasis and responding to stress.
