Mitogen‐activated‐protein‐kinase‐catalyzed phosphorylation of microtubule‐associated proteins, microtubule‐associated protein 2 and microtubule‐associated protein 4, induces an alteration in their function [PDF]

open access: yesEuropean Journal of Biochemistry, 1992
Mitogen‐activated protein kinase (MAPK), a serine/threonine‐specific protein kinase which is generally activated by stimulation with various growth factors and phorbol esters, utilizes microtubule‐associated protein (MAP) 2 as a good substrate in vitro.

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Linking cortical microtubule attachment and exocytosis [version 1; referees: 2 approved]

open access: yesF1000Research, 2017
Exocytosis is a fundamental cellular process whereby secreted molecules are packaged into vesicles that move along cytoskeletal filaments and fuse with the plasma membrane.

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Diverse Roles of Tubulin Polymerization Promoting Protein 3 (TPPP3) in Human Health and Disease

open access: yesCells
The tubulin polymerization promoting proteins (TPPPs) are a small family of conserved proteins originally characterized as microtubule binding proteins. TPPP1, the first identified member, both binds to and bundles microtubules.

Multicolour three dimensional structured illumination microscopy of immunolabeled plant microtubules and associated proteins

open access: yesPlant Methods, 2019
Background In the present work, we provide an account of structured illumination microscopy (SIM) imaging of fixed and immunolabeled plant probes. We take advantage of SIM, to superresolve intracellular structures at a considerable z-range and circumvent

Age-dependent accumulation of tau aggregation in Caenorhabditis elegans

open access: yesFrontiers in Aging, 2022
Aging is the primary risk factor for Alzheimer’s disease (AD) and related disorders (ADRDs). Tau aggregation is a hallmark of AD and other tauopathies.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
