S-100 Information for Pathologists


Acidic protein, 100% Soluble in ammonium sulfate at neutral pH (derivation of name). S100 protein family is multigenic group of nonubiquitous cytoplasmic EF-hand Ca2+-binding proteins, sharing significant structural similarities at both genomic and protein levels; S100 protein family has 24 known human members each coded by a separate gene; at least 19 on chromosome 1q21 (Hepat Mon 2012;12:e7240). Helps regulate cell contraction, motility, growth, differentiation, cell cycle progression, transcription and secretion. Structurally similar to calmodulin. Interpretation

Common Uses By Pathologists:

Common marker of neural tissue / lesions and melanoma. Differentiate plexiform schwannoma (S100+, Am J Surg Pathol 2005;29:1042) from MPNST (weak / negative / patchy). MelanA and MART1 appear to be superior to S100 for evaluating sentinel lymph nodes for melanoma (Am J Surg Pathol 2001;25:1039). Microscopic (histologic) images Images hosted on PathOut server:.
