Left, Mutations in the N-terminal DC domains are listed in the first column, followed by a column reporting their origin (familial, sporadic, or both), a column reporting the relative slope of the linearly-increasing portion of the response curve (normalized to the slope of the 13-pf wild-type curve, Fig. 2D, blue), and a column reporting whether they bind preferentially to 13-pf microtubules (+ = yes, − = no). Right, Mutations in the C-terminal DC domains are listed, followed by the same columns described above. See also Figure S4.
