CC -!- FUNCTION: Binds to actin monomers and regulates the organization of the
CC actin cytoskeleton (PubMed:26574597). At high concentrations, profilin
CC prevents the polymerization of actin, whereas it enhances it at low
CC concentrations (PubMed:29861135). At low concentrations, associates
CC with the poly-proline motif of formins to enhance actin filament
CC elongation rate (PubMed:29861135). Binds ACT1, ACT7 and ACT11 and
CC inhibits actin polymerization (PubMed:26578694). Coordinates the
CC stochastic dynamic properties of actin filaments by modulating formin-
CC mediated actin nucleation and assembly during axial cell expansion
CC (PubMed:26574597). Binds G-actin and poly-L-proline in vitro
CC (PubMed:19200149). Inhibits cell growth of various pathogenic fungal
CC strains (PubMed:30056100). May play a role as antifungal proteins in
CC the defense system against fungal pathogen attacks (PubMed:30056100).

CC ECO:0000269|PubMed:30056100}.
CC -!- SUBUNIT: Occurs in many kinds of cells as a complex with monomeric
CC actin in a 1:1 ratio. {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton {ECO:0000305}. Cytoplasm
CC {ECO:0000269|PubMed:17933902, ECO:0000269|PubMed:19200149}.
CC Note=Probably associated with cytoplasmic actin filaments.
CC {ECO:0000269|PubMed:19200149}.
CC -!- TISSUE SPECIFICITY: Expressed at low levels roots, leaves, stems,
CC flowers and siliques (PubMed:8771785, PubMed:8685262). Expressed in
CC leaf epidermal cells, trichomes and stem epidermal cells
CC (PubMed:19200149). Detected in phloem exudates (at protein level)
CC (PubMed:30056100). {ECO:0000269|PubMed:19200149,
CC ECO:0000269|PubMed:30056100, ECO:0000269|PubMed:8685262,
CC ECO:0000269|PubMed:8771785}.
CC -!- INDUCTION: Down-regulated by light. {ECO:0000269|PubMed:11340190}.
CC -!- DISRUPTION PHENOTYPE: Delayed germination (PubMed:11340190). In young
CC seedlings, excessive numbers of root hairs, abnormal raised cotyledons,
CC elongated hypocotyls, and elongated cells in the hypocotyl
CC (PubMed:11340190, PubMed:26574597). Defects in rosette leaf and
CC inflorescence development (PubMed:26160044).
CC {ECO:0000269|PubMed:11340190, ECO:0000269|PubMed:26160044,

CC -!- ALLERGEN: Causes an allergic reaction in human. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the profilin family. {ECO:0000305}.
