CC -!- FUNCTION: S100A9 is a calcium- and zinc-binding protein which plays a
CC prominent role in the regulation of inflammatory processes and immune
CC response (PubMed:12626582, PubMed:15331440, PubMed:20103766,
CC PubMed:8423249, PubMed:16258195, PubMed:19122197, PubMed:21325622). It
CC can induce neutrophil chemotaxis, adhesion, can increase the
CC bactericidal activity of neutrophils by promoting phagocytosis via
CC activation of SYK, PI3K/AKT, and ERK1/2 and can induce degranulation of
CC neutrophils by a MAPK-dependent mechanism (PubMed:12626582,
CC PubMed:15331440, PubMed:20103766). Predominantly found as calprotectin
CC (S100A8/A9) which has a wide plethora of intra- and extracellular
CC functions (PubMed:8423249, PubMed:16258195, PubMed:19122197). The
CC intracellular functions include: facilitating leukocyte arachidonic
CC acid trafficking and metabolism, modulation of the tubulin-dependent
CC cytoskeleton during migration of phagocytes and activation of the
CC neutrophilic NADPH-oxidase (PubMed:15331440, PubMed:21325622).
CC Activates NADPH-oxidase by facilitating the enzyme complex assembly at
CC the cell membrane, transferring arachidonic acid, an essential
CC cofactor, to the enzyme complex and S100A8 contributes to the enzyme
CC assembly by directly binding to NCF2/P67PHOX (PubMed:15642721,
CC PubMed:22808130). The extracellular functions involve pro-inflammatory,
CC antimicrobial, oxidant-scavenging and apoptosis-inducing activities
CC (PubMed:8423249, PubMed:19534726). Its pro-inflammatory activity
CC includes recruitment of leukocytes, promotion of cytokine and chemokine
CC production, and regulation of leukocyte adhesion and migration
CC (PubMed:15598812, PubMed:21487906). Acts as an alarmin or a danger
CC associated molecular pattern (DAMP) molecule and stimulates innate
CC immune cells via binding to pattern recognition receptors such as Toll-
CC like receptor 4 (TLR4) and receptor for advanced glycation endproducts
CC (AGER) (PubMed:19402754). Binding to TLR4 and AGER activates the MAP-
CC kinase and NF-kappa-B signaling pathways resulting in the amplification
CC of the pro-inflammatory cascade (PubMed:19402754, PubMed:22804476). Has
CC antimicrobial activity towards bacteria and fungi and exerts its
CC antimicrobial activity probably via chelation of Zn(2+) which is
CC essential for microbial growth (PubMed:19087201). Can induce cell death
CC via autophagy and apoptosis and this occurs through the cross-talk of
CC mitochondria and lysosomes via reactive oxygen species (ROS) and the
CC process involves BNIP3 (PubMed:19935772). Can regulate neutrophil
CC number and apoptosis by an anti-apoptotic effect; regulates cell
CC survival via ITGAM/ITGB and TLR4 and a signaling mechanism involving
CC MEK-ERK (PubMed:22363402). Its role as an oxidant scavenger has a
CC protective role in preventing exaggerated tissue damage by scavenging
CC oxidants (PubMed:22489132, PubMed:21912088). Can act as a potent
CC amplifier of inflammation in autoimmunity as well as in cancer
CC development and tumor spread (PubMed:16258195). Has transnitrosylase
CC activity; in oxidatively-modified low-densitity lipoprotein (LDL(ox))-
CC induced S-nitrosylation of GAPDH on 'Cys-247' proposed to transfer the
CC NO moiety from NOS2/iNOS to GAPDH via its own S-nitrosylated Cys-3
CC (PubMed:25417112). The iNOS-S100A8/A9 transnitrosylase complex is
CC proposed to also direct selective inflammatory stimulus-dependent S-
CC nitrosylation of multiple targets such as ANXA5, EZR, MSN and VIM by
CC recognizing a [IL]-x-C-x-x-[DE] motif (PubMed:25417112).

CC -!- SUBUNIT: Homodimer (PubMed:11851337, PubMed:16258195). Preferentially
CC exists as a heterodimer or heterotetramer with S100A8 known as
CC calprotectin (S100A8/A9) (PubMed:16258195, PubMed:17553524,
CC PubMed:19087201, PubMed:19122197, PubMed:8423249, PubMed:9083090,
CC PubMed:25417112). S100A9 interacts with ATP2A2 (By similarity). S100A9
CC interacts with AGER, and with the heterodimeric complex formed by TLR4
CC and LY96 in the presence of calcium and/or zinc ions (PubMed:19402754).
CC S100A9 binds quinoline-3-carboxamides in the presence of calcium and/or
CC zinc ions (PubMed:19402754). S100A9 interacts with amyloid-beta protein
CC 40 (PubMed:22457725). Calprotectin (S100A8/9) interacts with CEACAM3
CC and tubulin filaments in a calcium-dependent manner (PubMed:11708798).
CC Heterotetrameric calprotectin (S100A8/A9) interacts with ANXA6 and
CC associates with tubulin filaments in activated monocytes
CC (PubMed:18786929). Calprotectin (S100A8/9) interacts with NCF2/P67PHOX,
CC RAC1, RAC2, CYBA and CYBB (PubMed:15642721, PubMed:22808130).
CC Calprotectin (S100A8/9) interacts with NOS2 to form the iNOS-S100A8/A9
CC transnitrosylase complex; induced by LDL(ox) (PubMed:25417112).

CC -!- TISSUE SPECIFICITY: Calprotectin (S100A8/9) is predominantly expressed
CC in myeloid cells. Except for inflammatory conditions, the expression is
CC restricted to a specific stage of myeloid differentiation since both
CC proteins are expressed in circulating neutrophils and monocytes but are
CC absent in normal tissue macrophages and lymphocytes. Under chronic
CC inflammatory conditions, such as psoriasis and malignant disorders,
CC also expressed in the epidermis. Found in high concentrations at local
CC sites of inflammation or in the serum of patients with inflammatory
CC diseases such as rheumatoid, cystic fibrosis, inflammatory bowel
CC disease, Crohn's disease, giant cell arteritis, cystic fibrosis,
CC Sjogren's syndrome, systemic lupus erythematosus, and progressive
CC systemic sclerosis. Involved in the formation and deposition of
CC amyloids in the aging prostate known as corpora amylacea inclusions.
CC Strongly up-regulated in many tumors, including gastric, esophageal,
CC colon, pancreatic, bladder, ovarian, thyroid, breast and skin cancers.
