CC   -!- FUNCTION: Binds to actin and affects the structure of the cytoskeleton.
CC       At high concentrations, profilin prevents the polymerization of actin,
CC       whereas it enhances it at low concentrations. By binding to PIP2, it
CC       inhibits the formation of IP3 and DG (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Occurs in many kinds of cells as a complex with monomeric
CC       actin in a 1:1 ratio.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton {ECO:0000250}.
CC   -!- PTM: Phosphorylated by MAP kinases. {ECO:0000250}.
CC   -!- POLYMORPHISM: Several isoforms of the allergen exist due to
CC       polymorphism.
CC   -!- ALLERGEN: Causes an allergic reaction in human.
CC   -!- MISCELLANEOUS: The variability of the residues taking part of IgE-
CC       binding epitopes might be responsible of the difference in cross-
CC       reactivity among olive pollen cultivars, and between distantly related
CC       pollen species, leading to a variable range of allergy reactions among
CC       atopic patients. {ECO:0000305|PubMed:24146818}.
CC   -!- SIMILARITY: Belongs to the profilin family. {ECO:0000305}.
