Function

function

Binds to actin and affects the structure of the cytoskeleton. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations (By similarity).

Miscellaneous

The variability of the residues taking part of IgE-binding epitopes might be responsible of the difference in cross-reactivity among olive pollen cultivars, and between distantly related pollen species, leading to a variable range of allergy reactions among atopic patients.
