Figure Legend Snippet: ASK1, ASK2 and ASK3 C-terminal domains have different oligomerisation propensity. (A) Overview of domain architecture, and conservation of ASK1–3. (B) Size-exclusion chromatography of ASK1(1290–1374), ASK2(1216–1288) and ASK3(1241–1313), corresponding to regions of respective ASK proteins labelled ‘SAM’ domain in panel A. (C) Sedimentation velocity AUC analysis of ASK1, 2 and 3 domains at indicated concentrations spanning between 0.15 and 3.0 mg/mL (15–365 µM).
Techniques Used: Size-exclusion Chromatography, Sedimentation

Figure Legend Snippet: Comparisons of the ML-EH pairwise interaction of ASK3 with indicated SAM ML-EH structures.
Techniques Used:
Figure Legend Snippet: The ASK SAM domain ML-EH interface (A) Left: Schematic view of the ML-EH interface. Right: Electrostatic surfaces of ASK1–3 SAM domains (as calculated using APBS (37), with regions predicted to participate in ML-EH contacts outlined in yellow. Models of ASK1 and ASK2 were generated using MODELLER, based on the ASK3 SAM domain solved here.

Pairs of SAM domains participating in each type of interface overlaid based on the bottom SAM domain. The top SAM domain is offset, quantitated by an 18° shift of the α5 helix.
