Fig. 2. Comparison of the effect of axonemal motif (red triangles) and C-terminal tail peptides (green circles) on CBF and controls (dotted line, black solid squares); error bars indicate 1 s.e.m.; peptide concentrations: 0.33 µM. For sequences, see Table 1. (A) sequences derived from ß_I tubulin (433EEDFGEE and 438EEAEEEA). (B) sequences derived from ß_II tubulin (433QGEFEEE and 440EGEDEA). (C) sequences derived from ß_III tubulin (433GEMYEDD and 443SESQGPK). (D) sequences derived from ß_IV tubulin (433EGEFEEE and 439EAEEEVA). (E) sequences derived from ß_V tubulin (433EEAFEDE and 441EEEINE). (F) Concentration-dependent effect of the axonemal motif peptide (EGEFEEE), concentrations: 0.33 µM (blue squares), 0.033 µM (green circles) and 3.3 nM (red triangles).
