TTLL11 bound to microtubule
 Complex of TTLL11 and two tubulin dimers Complex of TTLL11 and two tubulin dimers 0 1 2 3 Homo sapiens Tubulin alpha-1B chain Homo sapiens 0.050204445
Native tubulin isolated from HEK 293T cells, unaligned regions are intrinsicly disordered

The C-terminal part of tubulin is intrinsicaly disordered thus not visible in the structure.

The original protein contains N-terminal Halo tag on a flexible linker so it is not visible in the map or included in the model. TTLL11 containes several instriscally disordered regions that are left out from the model.
