The interaction between the proline-rich peptides and the profilin isoforms is expressed in surface plasmon resonance response units. The peptides are derived from Ce-Ena (UNC-34, Y50D4C.1a) and are numbered according to their position in the protein sequence.

ND indicates not determined, [max] is the maximal concentration used, 92 μM for PFN-2, 126 μM for PFN-1, and 190 μM for human profilin I, respectively.
