CC   -!- FUNCTION: S100A8 is a calcium- and zinc-binding protein which plays a
CC       prominent role in the regulation of inflammatory processes and immune
CC       response. It can induce neutrophil chemotaxis and adhesion.
CC       Predominantly found as calprotectin (S100A8/A9) which has a wide
CC       plethora of intra- and extracellular functions. The intracellular
CC       functions include: facilitating leukocyte arachidonic acid trafficking
CC       and metabolism, modulation of the tubulin-dependent cytoskeleton during
CC       migration of phagocytes and activation of the neutrophilic NADPH-
CC       oxidase. Activates NADPH-oxidase by facilitating the enzyme complex
CC       assembly at the cell membrane, transferring arachidonic acid, an
CC       essential cofactor, to the enzyme complex and S100A8 contributes to the
CC       enzyme assembly by directly binding to NCF2/P67PHOX. The extracellular
CC       functions involve pro-inflammatory, antimicrobial, oxidant-scavenging
CC       and apoptosis-inducing activities. Its pro-inflammatory activity
CC       includes recruitment of leukocytes, promotion of cytokine and chemokine
CC       production, and regulation of leukocyte adhesion and migration. Acts as
CC       an alarmin or a danger associated molecular pattern (DAMP) molecule and
CC       stimulates innate immune cells via binding to pattern recognition
CC       receptors such as Toll-like receptor 4 (TLR4) and receptor for advanced
CC       glycation endproducts (AGER). Binding to TLR4 and AGER activates the
CC       MAP-kinase and NF-kappa-B signaling pathways resulting in the
CC       amplification of the pro-inflammatory cascade. Has antimicrobial
CC       activity towards bacteria and fungi and exerts its antimicrobial
CC       activity probably via chelation of Zn(2+) which is essential for
CC       microbial growth. Can induce cell death via autophagy and apoptosis and
CC       this occurs through the cross-talk of mitochondria and lysosomes via
CC       reactive oxygen species (ROS) and the process involves BNIP3. Can
CC       regulate neutrophil number and apoptosis by an anti-apoptotic effect;
CC       regulates cell survival via ITGAM/ITGB and TLR4 and a signaling
CC       mechanism involving MEK-ERK. Its role as an oxidant scavenger has a
CC       protective role in preventing exaggerated tissue damage by scavenging
CC       oxidants. Can act as a potent amplifier of inflammation in autoimmunity
CC       as well as in cancer development and tumor spread. The iNOS-S100A8/A9
CC       transnitrosylase complex directs selective inflammatory stimulus-
CC       dependent S-nitrosylation of GAPDH and probably multiple targets such
CC       as ANXA5, EZR, MSN and VIM by recognizing a [IL]-x-C-x-x-[DE] motif;
CC       S100A8 seems to contribute to S-nitrosylation site selectivity.

CC       signaling is inhibited by paquinimod. {ECO:0000250|UniProtKB:P27005}.
CC   -!- SUBUNIT: Homodimer. Preferentially exists as a heterodimer or
CC       heterotetramer with S100A9 known as calprotectin (S100A8/A9). S100A8
CC       interacts with AGER, ATP2A2 and with the heterodimeric complex formed
CC       by TLR4 and LY96 (By similarity). Interacts with GAPDH. Calprotectin
CC       (S100A8/9) interacts with CEACAM3 and tubulin filaments in a calcium-
CC       dependent manner. Heterotetrameric calprotectin (S100A8/A9) interacts
CC       with ANXA6 and associates with tubulin filaments in activated
CC       monocytes. S100A8 and calprotectin (S100A8/9) interact with
CC       NCF2/P67PHOX, RAC1 and RAC2. Calprotectin (S100A8/9) interacts with
CC       CYBA and CYBB. Calprotectin (S100A8/9) interacts with NOS2 to form the
CC       iNOS-S100A8/A9 transnitrosylase complex; induced by LDL(ox)
CC       (PubMed:25417112). {ECO:0000250, ECO:0000269|PubMed:11708798,

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.
