RN [2] RP 3D-STRUCTURE MODELING, AND DISULFIDE BOND.

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 similarity). CC {ECO:0000250}. CC -!- SUBUNIT: Occurs in many kinds of cells as a complex with monomeric CC actin in a 1:1 ratio. {ECO:0000250}. 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}.
