S100 Calcium-Binding Protein A4

An S100 protein characterized by four helix bundles that form N- and C-terminal EF HAND MOTIFS. It functions as a homodimer and interacts with both intracellular and extracellular signaling proteins. Aberrant S100A4 activity is associated with NEOPLASM METASTASIS; FIBROSIS; and RHEUMATOID ARTHRITIS.
