Ranaspumin-2 (Rsn-2) is a monomeric, 11 kDa surfactant protein identified as one of the major foam nest components of the túngara frog (Engystomops pustulosus). This has been confirmed by experiments showing that recombinant Rsn-2 provides a significant reduction in the surface tension of aqueous solutions at concentrations as low as 10 μg mL−1 (Mackenzie et al., 2009).

Rsn-2 has no sequence similarity to hydrophobins, lipopeptides, or lung surfactants, involves no associated lipid, and is active at much lower concentrations than are normally required for foaming of denatured proteins. Consequently, it represents a new class of surfactant protein (Mackenzie et al., 2009).
