S100A4 also known as metastasin or MTS1 is a protein with a molecular weight of approximately 12 kDa. It functions by binding calcium which induces conformational changes aiding in its interaction with target proteins. S100A4 is part of the S100 family of proteins characterized by two EF-hand calcium-binding motifs. Expression of S100A4 is observed in various cell types including fibroblasts endothelial cells and several tumor cells where it contributes to processes like cell motility invasion and angiogenesis.
Biological function summary
The role of S100A4 extends beyond mere calcium binding; it associates with the cytoskeleton promoting cell structures related to movement and metastasis. It does not act alone but often partners with proteins like myosin IIA to regulate cytoskeletal dynamics. Additionally S100A4 modulates extracellular matrix components and interacts with signaling pathways that control cancer progression making it significant in both normal physiological contexts and pathological states.
Pathways
Functional activities of S100A4 integrate into important pathways involved in cellular movement and metastasis. S100A4 plays roles in the regulation of the Wnt/β-catenin pathway which is pivotal for cell-cell interaction and fate determination. It also interacts with matrix metalloproteinases like MMPs thereby managing processes of tissue invasion and remodeling essential in cancer metastasis. Other pathways influencing cell adhesion and signal transduction may indirectly involve S100A4 through related proteins.
Elevated S100A4 levels have implications in cancer particularly in enhancing metastasis in breast and colorectal cancers. The protein promotes tumor developments by inducing changes in the tumor microenvironment making it a target of interest in oncology. S100A4 also interacts with proteins like p53 and β-catenin which are critical in the pathology of tumors. Moreover S100A4 contributes to fibrotic diseases accentuating tissue remodeling activities by modulating fibroblast behavior and extracellular matrix deposition.
