Extended Data Fig. 2: Differences in the tektin bundle across mammalian motile cilia.
From: Structural diversity of axonemes across mammalian motile cilia

Cross-sections of doublet microtubules from the indicated cilia types and species. Tektins (TEKT1-5), Tektin-like protein 1 (TEKTL1), tektin-interacting protein 1 (TEKTIP1), and RIBC1/2 are colored according to the legend. Other microtubule-binding proteins are in grey and tubulin is in white. Structures were determined by single-particle analysis (SPA) except for oviductal cilia from Sus scrofa, which was determined by subtomogram averaging (STA).
