SPAG16 is a Bifunctional Gene Regulating Male Fertility
… to the structure and function of the “9 + 2” axoneme. The “9 + 2” axoneme provides the cytoskeletal core of all eukaryotic motile cilia and flagella. In Chlamydomonas, the Pf20 gene encodes a single protein present in the central pair of the axoneme. Loss of Pf20 prevents central pair assembly …

Dynamics of Cilia and Flagella
… highly conserved structure called the axoneme, whose characteristic architecture is based on a cylindrical arrangement of elastic filaments (microtubules). In the presence of a chemical fuel (ATP), molecular motors (dynein) exert shear forces between neighbouring microtubules, leading …

Flagellum assembly in protozoan parasites
… and microgametes. Our findings revealed axonemes coiling around the nucleus in opposite directions, forming a central axonemal band. We also discovered that the nucleus tightly coils around the axoneme in microgametes before exflagellation. This detailed 3D organisation of flagellated …

Defining the molecular composition and organisation of Transition fibres in Trypanosoma brucei and their roles in flagellar assembly and length control
… core structure, composed of a microtubule-based axoneme that runs through its core. The axonemal microtubules are nucleated by a barrel shaped microtubule-organising basal body. Transition fibres (TFs) are appendage structures surrounding the distal end of the mature basal body that enable …

A Novel Collapsing Response Mediator Protein 2 Binding Domain for Kinesin Light Chain 3
… cilia and sperm flagella. Both contain an axoneme and both require presence of ODF2. Therefore, primary cilia can be used as a partial model to study the assembly of sperm flagella. Recently, we have shown that Collapsin Response Mediator Protein 2 is required for ciliogenesis, localizes to …

Aspectos da morfologia e biologia de Scinax ruber (Laurenti, 1768) com comentários taxonômicos (Amphibia, Anura, Hylidae)
… 9) flagellum of spermatozoa consisting of an axoneme and an axial fiber connected by an undulating membrane. Taxonornic notes are provided. Scina.x alter (B. Lutz, 1973) is confirmed as ajunior synonym of S. ruber. The existence in Ecuador of a species closely related to S. ruber is reported. …

The role of intraflagellar transport during the disassembly of the Leishmania mexicana flagellum
… mutant. It had a very short but otherwise normal axoneme but a large mass of unorganised material at the exit of the flagellar pocket, which created a bulge. The underlying cause of this mutant was hypothesised to be a defect in IFT. However, analyses showed that a large 27 kb deletion, containing …

Endogenous Gene Tagging of pfr2 and pfr5 in Trypanosoma cruzi Using CRISPR/Cas9
… that lies alongside the (9 + 2) microtubular axoneme, beginning at the flagellar pocket and extending to the flagellar tip. The PFR has only been observed within the phylums Euglenozoa and Dinoflagellata, although many eukaryotic organisms with long flagella have extra-axonemal structures that …

The Role of Estrogen Receptor Alpha in Epididymal Sperm Structure and Function
… from the epididymis were found to have abnormal axoneme coiling and increased incidence of spontaneous acrosome reactions, both of which are consistent with defective regulation of the epididymal fluid. This was confirmed by incubating ERalphaKO sperm in a more wildtype-like osmotic environment, …

Role of WDR35 in the formation of functional cilia
… the cargo along microtubules ‘railways’ of the axoneme. IFTs are known to assemble in two protein complexes, IFTA and IFTB protein complexes. IFT-B complex known to be made of 16 different proteins mediate anterograde transport with the help of kinesin motors, and IFT-A complex made of 6 …
