(A) The tertiary structure of TCF7L2 protein predicted by Robetta server. (B) Ramachandran plot for the diabetes-causing protein of TCF7L2 statistics showed most favored regions in (red color), additional allowed regions in (yellow, generously allowed regions in (light brown) and disallowed regions in (white color). (C) ERRAT server interpreted results in a graph showing the distribution of protein residues in error or non-error regions for TCF7L2 protein. The red lines are errors, and the yellow lines are warnings.
