Type Comment Proteins
PRF5_ARATH function Binds to actin monomers and regulates the organization of the actin cytoskeleton (PubMed:29861135). At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations (PubMed:29861135). At low concentrations, associates with the poly-proline motif of formins to enhance actin filament elongation rate (PubMed:29861135). Acts redundantly with PRF4 to regulate apical actin polymerization at the tip of pollen tube and control polarized pollen tube growth (PubMed:26433093). Functions probably by favoring formin-mediated actin polymerization at pollen tube tips (PubMed:26433093).
PRF5_ARATH similarity Belongs to the profilin family.
PRF5_ARATH tissue specificity Specifically expressed in mature pollen grains (PubMed:11977080, PubMed:16361517, PubMed:8685262, PubMed:8771785). Expressed in germinating pollen grains (PubMed:11977080, PubMed:8771785). Expressed in growing pollen tubes (at protein level) (PubMed:11977080).
