Frataxin mRNA Isoforms in FRDA Patients and Normal Subjects: Effect of Tocotrienol Supplementation

Figure 4

Structural comparison of human FXN-1 with FXN-2 and FXN-3. Sequence and structural alignment of FXN-1 (1EKG, depicted in blue) with the computed 3D models of FXN-2 and FXN-3 (colored in green and red, resp.). The secondary structure of FXN-1 is also reported along the structural alignment (helices: red line; beta sheets: yellow arrow). Functional residues of the anionic patch and residues involved in protein stability are highlighted in black and orange, respectively, and are conserved in all the isoforms.
