Cryo-EM of α-tubulin isotype-containing microtubules revealed a contracted structure of α4A/β2A microtubules [PDF]

open access: yesActa Biochimica et Biophysica Sinica, 2023
Microtubules are hollow α/β-tubulin heterodimeric polymers that play critical roles in cells. In vertebrates, both α- and β-tubulins have multiple isotypes encoded by different genes, which are intrinsic factors in

Mechanistic Analysis of CCP1 in Generating ΔC2 α-Tubulin in Mammalian Cells and Photoreceptor Neurons [PDF]

open access: yesBiomolecules, 2023
An important post-translational modification (PTM) of α-tubulin is the removal of amino acids from its C-terminus. Removal of the C-terminal tyrosine residue yields detyrosinated α-tubulin, and subsequent removal of the penultimate glutamate residue ...

Reduced acetylated α-tubulin in SPAST hereditary spastic paraplegia patient PBMCs [PDF]

open access: yesFrontiers in Neuroscience, 2023
HSP-SPAST is the most common form of hereditary spastic paraplegia (HSP), a neurodegenerative disease causing lower limb spasticity. Previous studies using HSP-SPAST patient-derived induced pluripotent stem cell cortical neurons have shown that patient ...

Accessibility of the unstructured α-tubulin C-terminal tail is controlled by microtubule lattice conformation [PDF]

open access: yeseLife
Microtubules are cytoskeletal filaments that self-assemble from the protein tubulin, a heterodimer of α-tubulin and β-tubulin, and are important for cell mechanics, migration, and division.

Metabolic regulation of cytoskeleton functions by HDAC6-catalyzed α-tubulin lactylation [PDF]

open access: yesNature Communications
Posttranslational modifications (PTMs) of tubulin, termed the “tubulin code”, play important roles in regulating microtubule functions within subcellular compartments for specialized cellular activities.

Molecular Docking of Cryptoconcatones to α-Tubulin and Related Pironetin Analogues [PDF]

open access: yesPlants, 2023
Cryptoconcatones A-L represent a series of 12 dihydropyrone derivatives isolated from the evergreen tree Cryptocarya concinna Hance, which is well distributed in southeast Asia.

α-Tubulin acetylation at lysine 40 regulates dendritic arborization and larval locomotion by promoting microtubule stability in Drosophila. [PDF]

open access: yesPLoS ONE, 2023
Posttranslational modification of tubulin increases the dynamic complexity and functional diversity of microtubules. Acetylation of α-tubulin at Lys-40 is a highly conserved posttranslational modification that has been shown to improve the flexibility ...

Nutritional stress-induced regulation of microtubule organization and mRNP transport by HDAC1 controlled α-tubulin acetylation [PDF]

open access: yesCommunications Biology, 2023
In response to nutritional stress, microtubules in cells of the Drosophila female germline are depleted from the cytoplasm and accumulate cortically. This triggers aggregation of mRNPs into large processing bodies (P-bodies) and oogenesis arrest.

α-tubulin detyrosination fine-tunes kinetochore-microtubule attachments [PDF]

open access: yesNature Communications
Post-translational cycles of α-tubulin detyrosination and tyrosination generate microtubule diversity, the cellular functions of which remain largely unknown.

Targeting plasmodium α-tubulin-1 to block malaria transmission to mosquitoes [PDF]

open access: yesFrontiers in Cellular and Infection Microbiology, 2023
Plasmodium ookinetes use an invasive apparatus to invade mosquito midguts, and tubulins are the major structural proteins of this apical complex. We examined the role of tubulins in malaria transmission to mosquitoes.
