General annotation (Comments)

Function

Calcium-binding protein. Has antimicrobial activity towards bacteria and fungi. Important for resistance to invasion by pathogenic bacteria. Up-regulates transcription of genes that are under the control of NF-kappa-B. Plays a role in the development of endotoxic shock in response to bacterial lipopolysaccharide (LPS) By similarity. Promotes tubulin polymerization when unphosphorylated. Promotes phagocyte migration and infiltration of granulocytes at sites of wounding. Plays a role as a pro-inflammatory mediator in acute and chronic inflammation and up-regulates the release of IL8 and cell-surface expression of ICAM1. Extracellular calprotectin binds to target cells and promotes apoptosis. Antimicrobial and proapoptotic activity is inhibited by zinc ions. Ref.11 Ref.14 Ref.15 Ref.16 Ref.20 Ref.21 Ref.23

Subunit structure

Homodimer. Heterotetramer with S100A8. Component of the heterotetrameric calprotectin complex containing two copies each of S100A8 and S100A9. Interacts with CEACAM3 and tubulin filaments in a calcium-dependent manner. Heterotetrameric calprotectin interacts with ANXA6 and associates with tubulin filaments in activated monocytes. May interact with components of the intermediate filaments in monocytes and epithelial cells. The homodimer interacts with AGER and with the heterodimeric complex formed by TLR4 and LY96 in the presence of calcium and/or zinc ions. The homodimer binds quinoline-3-carboxamides in the presence of calcium and/or zinc ions. Ref.14 Ref.16 Ref.20 Ref.21 Ref.23 Ref.12 Ref.13 Ref.17 Ref.24 Ref.25

Subcellular location

Secreted. Cytoplasm. Cytoplasmcytoskeleton. Cell membrane; Peripheral membrane protein. Note: Associates with tubulin filaments in activated monocytes. Targeted to the cell surface upon calcium influx. Released from blood leukocytes upon exposure to CSF2/GM-CSF, bacterial lipopolysaccharide (LPS) and during inflammatory processes. Serum levels are high in patients suffering from chronic inflammation. Ref.11 Ref.15 Ref.23 Ref.12 Ref.17

Tissue specificity

Expressed by macrophages in acutely inflammed tissues and in chronic inflammation. Detected in peripheral blood leukocytes, in neutrophils and granulocytes. Detected at sites of vascular inflammation (at protein level). Also expressed in epithelial cells constitutively or induced during dermatoses. Ref.11 Ref.15 Ref.12 Ref.1 Ref.2

Post-translational modification

Phosphorylated. Phosphorylation inhibits activation of tubulin polymerization. Ref.14 Ref.8 Ref.18 Ref.19

Sequence similarities

Belongs to the S-100 family.

Contains 2 EF-hand domains.

Mass spectrometry

Molecular mass is 13115 Da from positions 2 - 114. Determined by MALDI. Ref.24
