1CQA - PubMed Abstract: 
The profilins are a group of ubiquitous actin monomer binding proteins that are responsible for regulating the normal distribution of filamentous actin networks in eukaryotic cells. Profilins also bind polyphosphoinositides, which can disrupt the profilin-action complex, and proline-rich ligands which localize profilin to sites requiring extensive actin filament accumulation. Profilins represent cross-reactive allergens for almost 20 % of all pollen allergic patients.
