CC -!- FUNCTION: Plays important roles in the innate immune response as
CC effector of glucocorticoid-mediated responses and regulator of the
CC inflammatory process. Has anti-inflammatory activity. Plays a role in
CC glucocorticoid-mediated down-regulation of the early phase of the
CC inflammatory response. Contributes to the adaptive immune response by
CC enhancing signaling cascades that are triggered by T-cell activation,
CC regulates differentiation and proliferation of activated T-cells.
CC Promotes the differentiation of T-cells into Th1 cells and negatively
CC regulates differentiation into Th2 cells (By similarity). Has no effect
CC on unstimulated T-cells. Negatively regulates hormone exocytosis via
CC activation of the formyl peptide receptors and reorganization of the
CC actin cytoskeleton (By similarity). Has high affinity for Ca(2+) and
CC can bind up to eight Ca(2+) ions (By similarity). Displays Ca(2+)-
CC dependent binding to phospholipid membranes (By similarity). Plays a
CC role in the formation of phagocytic cups and phagosomes. Plays a role
CC in phagocytosis by mediating the Ca(2+)-dependent interaction between
CC phagosomes and the actin cytoskeleton (By similarity).

CC ECO:0000250|UniProtKB:P19619}.
CC -!- FUNCTION: [Annexin Ac2-26]: Functions at least in part by activating
CC the formyl peptide receptors and downstream signaling cascades.
CC Promotes chemotaxis of granulocytes and monocytes via activation of the
CC formyl peptide receptors. Promotes rearrangement of the actin
CC cytoskeleton, cell polarization and cell migration. Promotes resolution
CC of inflammation and wound healing. Acts via neutrophil N-formyl peptide
CC receptors to enhance the release of CXCL2.
CC {ECO:0000250|UniProtKB:P04083}.
CC -!- SUBUNIT: Homodimer; non-covalently linked (By similarity). Homodimer;
CC linked by transglutamylation. Homodimers linked by transglutamylation
CC are observed in placenta, but not in other tissues. Interacts with
CC S100A11. Heterotetramer, formed by two molecules each of S100A11 and
CC ANXA1 (By similarity). Interacts with DYSF (By similarity). Interacts
CC with EGFR (By similarity). {ECO:0000250|UniProtKB:P04083,

CC {ECO:0000250|UniProtKB:P10107}. Note=Colocalizes with actin fibers at
CC phagocytic cups. Secreted, at least in part via exosomes and other
CC secretory vesicles. Detected in exosomes and other extracellular
CC vesicles. Secretion is increased in response to wounding and
CC inflammation (By similarity). Alternatively, the secretion is dependent
CC on protein unfolding and facilitated by the cargo receptor TMED10; it
CC results in the protein translocation from the cytoplasm into ERGIC
CC (endoplasmic reticulum-Golgi intermediate compartment) followed by
CC vesicle entry and secretion (By similarity). Detected in gelatinase
CC granules in resting neutrophils. Neutrophil adhesion to endothelial
CC cells stimulates secretion via gelatinase granules, but foreign
CC particle phagocytosis has no effect. Displays calcium-dependent binding
CC to phospholipid membranes (By similarity).
CC {ECO:0000250|UniProtKB:P04083, ECO:0000250|UniProtKB:P10107}.
CC -!- DOMAIN: The full-length protein can bind eight Ca(2+) ions via the
CC annexin repeats. Calcium binding causes a major conformation change
CC that modifies dimer contacts and leads to surface exposure of the N-
CC terminal phosphorylation sites; in the absence of Ca(2+), these sites
CC are buried in the interior of the protein core. The N-terminal region
CC becomes disordered in response to calcium-binding.
CC {ECO:0000250|UniProtKB:P19619}.
CC -!- PTM: Phosphorylated by protein kinase C, EGFR and TRPM7. Phosphorylated
CC in response to EGF treatment. {ECO:0000250|UniProtKB:P04083}.
CC -!- PTM: Sumoylated. {ECO:0000250|UniProtKB:P10107}.
CC -!- PTM: Proteolytically cleaved by cathepsin CTSG to release the active N-
CC terminal peptide Ac2-26. {ECO:0000250|UniProtKB:P04083}.
CC -!- MISCELLANEOUS: Was originally identified as calcium and phospholipid
CC binding protein that displays Ca(2+)-dependent binding to phospholipid
CC membranes and can promote membrane aggregation in vitro. Was initially
CC identified as inhibitor of phospholipase A2 activity (in vitro).
CC Inhibition of phospholipase activity is mediated via its phospholipid
CC binding activity that limits the access of phospholipase to its
CC substrates. {ECO:0000250|UniProtKB:P10107}.
CC -!- SIMILARITY: Belongs to the annexin family. {ECO:0000255|PROSITE-
CC ProRule:PRU01245, ECO:0000305}.
CC -!- CAUTION: Was originally thought to originate from the sponge Geodia
CC cydonium, but, on the basis of phylogenetic studies (Ref.2) it seems
CC very probable that the DNA sequence coding for this protein comes from
CC a rodent as agreed by the original authors (Ref.3).
