Profilins purified from higher plants bind to actin from cardiac muscle and to actin from a green alga.
Profilins purified from Zea mays transiently enhance the viscosity of polymerizing cardiac actin at ratios (profilin: actin) < 1, but lower the viscosity at higher ratios. Specific binding of actin from the alga Chara corallina to higher plant profilins suggests strict conservation of interaction between both proteins in plants.
