FIGURE 1:

The architecture of the N-DRC in the Chlamydomonas wild-type axoneme. (A) Three-dimensional isosurface rendering of the averaged 96-nm repeat shows the nexin linker (green) of the N-DRC and other axonemal structures (gray) in a longitudinal front view (proximal is on the left). (B) Magnified surface rendering of the N-DRC shows the nexin linker (green) and the base plate (blue) in a longitudinal bottom view (from the central pair toward the doublet microtubule). For better visualization of the N-DRC, other axonemal structures are not shown in B. Arrowheads indicate OID linkers. a–g, inner arms a–g; IDA, inner dynein arm; L1, L1 protrusion; L2, L2 protrusion; ODA, outer dynein arm; RS1 and RS2, radial spokes 1 and 2.
