Figure 7. Intersectin(SH3(E)-DH) is monomeric.

Figure 7

a) Elution profile of Intersectin(SH3(E)-DH) from a Superdex-75 size-exclusion column. Intersectin(SH3(E)-DH) elutes as a single peak between the elution volumes of ovalbumin (44 kDa) and chymotrypsinogen (25 kDa). b) Analytical ultracentrifugation (AUC) analysis of intersectin(SH3(E)-DH). The top curve is at 14,000 rpm and the bottom at 20,000 rpm. Shown below are the residuals for fits to the data. The data fit to an effective molecular weight (σ) of 1.5. c) Predicted σ values of different oligomeric states of intersectin(SH3(E)-DH). A σ value of 1.5 correlates to a molecular weight of 32 kDa, based on AUC analysis of the 12.9 kDa protein profillin (σ = 0.6092).
