S100a8 Gene Summary [Mouse]
Predicted to enable calcium ion binding activity and calcium-dependent protein binding activity. Acts upstream of or within astrocyte development and positive regulation of peptide secretion. Predicted to be located in cytosol; extracellular space; and intermediate filament cytoskeleton. Predicted to be part of S100A8 complex and calprotectin complex. Predicted to be active in cytoplasm. Is expressed in several structures, including bone marrow; extraembryonic component; liver; mesometrium; and placenta. Human ortholog(s) of this gene implicated in myocarditis. Orthologous to human S100A8 (S100 calcium binding protein A8). [provided by Alliance of Genome Resources, Jul 2025]
