Birch pollen profilin: structural organization and interaction with poly-(L-proline)

FEBS Lett. 1997 Jul 14;411(2-3):291-5

Authors: Domke T, Federau T, SchlÃ¼ter K, Giehl K, Valenta R, Schomburg D, Jockusch BM

The secondary structure of birch pollen profilin, a potent human allergen, was elucidated by multidimensional nuclear magnetic resonance (NMR), as a prerequisite to study the interaction of this profilin with ligands for its poly-(L-proline) (PLP)-binding site. The chemical shifts of the 15N-labeled backbone amide groups were used to monitor complex formation with various PLP peptides. Titration with deca-L-proline (P10) yielded a KD of 0.2 mM. P8 was the shortest PLP to provoke a significant reaction. (GP5)3G bound significantly, confirming the interaction between profilins and the protein VASP containing this motif. Birch profilin interacted also with GP6GP5, found in the cyclase-associated protein (CAP), a suspected profilin ligand.
