Immunopharmacology Comments
S100A11 is a pro-inflammatory calcium-binding protein. Elevated S100A11 has been reported as a marker of disease activity and extramuscular manifestations in inflammatory myopathies [1], and as a diagnostic marker that can distinguish systemic lupus erythematosus patients from healthy controls [4,11].

General Comments
S100A11 is expressed in a variety of human tissues including skin, placenta, lung, PBMCs, kidney and heart, but it is not expressed in the brain [6]. Expression is elevated in some cancers [8,10], and in chronic inflammatory diseases [2,4]. The protein localises in the nucleus, cytoplasm and cell periphery [3,5,7]. S100A11 contains 2 EF-hand Ca2+-binding motifs.
