OX NCBI_TaxID=4212; RN [1] RP NUCLEOTIDE SEQUENCE [MRNA]. RC TISSUE=Pollen; RX PubMed=15237444; DOI=10.3748/wjg.v10.i14.2103; RA Tao A.L., He S.H.; RT "Bridging PCR and partially overlapping primers for novel allergen gene RT cloning and expression insert decoration."; RL World J. Gastroenterol. 10:2103-2108(2004). 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 -!- ALLERGEN: Causes an allergic reaction in human. CC -!- SIMILARITY: Belongs to the profilin family. {ECO:0000305}.
