S100 proteins are a family of proteins known for their role in a variety of cellular pathways and diseases. This blog post will catch you up on the latest research on these important proteins.
- The S100 protein family consists of 21 proteins that exhibit structural similarity. However, many of the proteins differ in their function1.
- Calcium binding activates S100 proteins. S100 proteins undergo a conformation change, thereby allowing interaction with other proteins2.
- S100 proteins regulate levels of nucleic acids and a variety of proteins such as enzymes, receptors and transcription factors3.
- Some S100 proteins interact with intracellular targets. An example is S100A6, which can bind p53 in the cytosol to regulate apoptosis3.
- Some S100 proteins interact with extracellular targets. These interactions include binding to extracellular receptors or binding extracellular circulating proteins3.
- S100 proteins are involved in many important cellular processes such as apoptosis, inflammation, energy metabolism and proliferation3.
- S100 proteins have been implicated in a variety of cancers1,2. The specific ways S100 proteins are involved in cancer will be discussed in a future post.
