Human S100A11 Antibody

S100A11 (also S100C and calgizzarin) is a 10‑12 kDa member of the S100 family, EF-hand superfamily of Ca‑binding proteins. It is produced by smooth muscle and keratinocytes. Intracellularly, it suppresses growth; extracellularly, it exists as both a monomer, homodimer, and heterodimer with S100B, binds to RAGE, induces EGF, and promotes cell growth. Human S100A11 is 105 amino acids (aa) in length. It contains two EF-hand motifs (aa 13‑49 and 55‑90) and one high-affinity Ca‑binding site (aa 68‑79), and binds annexin I with its C-terminal half. There may be one alternative splice form that apparently contains a series of mutations over aa 61‑79 and shows 90% overall aa identity to the standard form. Full-length human S100A11 shares 78% and 82% aa identity with mouse and porcine S100A11, respectively.
