Chlamydomonas Basal Bodies as Flagella Organizing Centers

open access: yesCells, 2018
During ciliogenesis, centrioles convert to membrane-docked basal bodies, which initiate the formation of cilia/flagella and template the nine doublet microtubules of the flagellar axoneme.

Role of the microtubules in the electrical activity of the primary cilium of renal epithelial cells

open access: yesFrontiers in Molecular Biosciences, 2023
The primary cilium is a non-motile sensory organelle that transduces environmental cues into cellular responses. It comprises an axoneme, a core of nine doublet microtubules (MTs) coated by a specialized membrane populated by receptors, and a high ...

Cryo-EM of dynein microtubule-binding domains shows how an axonemal dynein distorts the microtubule

open access: yeseLife, 2019
Dyneins are motor proteins responsible for transport in the cytoplasm and the beating of axonemes in cilia and flagella. They bind and release microtubules via a compact microtubule-binding domain (MTBD) at the end of a coiled-coil stalk.

Axonemal Dynein Arms [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2016
Axonemal dyneins form the inner and outer rows of arms associated with the doublet microtubules of motile cilia. These enzymes convert the chemical energy released from adenosine triphosphate (ATP) hydrolysis into mechanical work by causing the doublets to slide with respect to each other.

Mechanisms of Regulation in Intraflagellar Transport

open access: yesCells, 2022
Cilia are eukaryotic organelles essential for movement, signaling or sensing. Primary cilia act as antennae to sense a cell’s environment and are involved in a wide range of signaling pathways essential for development. Motile cilia drive cell locomotion

Cfap91-Dependent Stability of the RS2 and RS3 Base Proteins and Adjacent Inner Dynein Arms in Tetrahymena Cilia

open access: yesCells, 2022
Motile cilia and eukaryotic flagella are specific cell protrusions that are conserved from protists to humans. They are supported by a skeleton composed of uniquely organized microtubules—nine peripheral doublets and two central singlets (9 × 2 + 2 ...

Microtubular Dysfunction and Male Infertility

open access: yesThe World Journal of Men's Health, 2020
Microtubules are the prime component of the cytoskeleton along with microfilaments. Being vital for organelle transport and cellular divisions during spermatogenesis and sperm motility process, microtubules ascertain functional capacity of sperm. Also,

Cryo electron tomography with volta phase plate reveals novel structural foundations of the 96-nm axonemal repeat in the pathogen Trypanosoma brucei

open access: yeseLife, 2019
The 96-nm axonemal repeat includes dynein motors and accessory structures as the foundation for motility of eukaryotic flagella and cilia. However, high-resolution 3D axoneme structures are unavailable for organisms among the Excavates, which include ...

TTC26/DYF13 is an intraflagellar transport protein required for transport of motility-related proteins into flagella

open access: yeseLife, 2014
Cilia/flagella are assembled and maintained by the process of intraflagellar transport (IFT), a highly conserved mechanism involving more than 20 IFT proteins. However, the functions of individual IFT proteins are mostly unclear.

Regulation of motor activity of ciliary outer-arm dynein by the light chain 1; Implications from the structure of the light chain bound to the microtubule-binding domain of the heavy chain

open access: yesBiophysics and Physicobiology, 2023
Ciliary bending movements are powered by motor protein axonemal dyneins. They are largely classified into two groups, inner-arm dynein and outer-arm dynein. Outer-arm dynein, which is important for the elevation of ciliary beat frequency, has three heavy
