S100 proteins

S100 proteins are a group of small proteins found in various tissues throughout the body, primarily in the brain and skin. They play essential roles in regulating important processes like cell growth, inflammation, and calcium signaling. S100 proteins can also act as markers for certain diseases, including neurodegenerative disorders and cancers. Their ability to bind calcium ions influences many cellular functions, making them crucial for maintaining health and responding to stress. Researchers study S100 proteins to better understand their functions and potential as targets for new treatments.
