A mathematical understanding of how cytoplasmic dynein walks on microtubules [PDF]

Royal Society Open Science, 2018
Cytoplasmic dynein 1 (hereafter referred to simply as dynein) is a dimeric motor protein that walks and transports intracellular cargos towards the minus end of microtubules. In this article, we formulate, based on physical principles, a mechanical model

Lipid Droplet‐Localized Spindle Apparatus Coiled‐Coil Protein 1 Regulates Lipid Droplet Distribution

Advanced Science, EarlyView.
SPDL1‐L, a long isoform of SPDL1, is identified as a bona fide lipid droplet‐associated protein that acts as a dynein adaptor to drive perinuclear clustering of lipid droplets. By linking lipid droplets to the microtubule network, SPDL1‐L extends the function of SPDL1 beyond mitosis and contributes to lipid droplet organization and nuclear remodeling ...

The human cytoplasmic dynein interactome reveals novel activators of motility

eLife, 2017
In human cells, cytoplasmic dynein-1 is essential for long-distance transport of many cargos, including organelles, RNAs, proteins, and viruses, towards microtubule minus ends.

The Generation of Dynein Networks by Multi-Layered Regulation and Their Implication in Cell Division

Frontiers in Cell and Developmental Biology, 2020
Cytoplasmic dynein-1 (hereafter referred to as dynein) is a major microtubule-based motor critical for cell division. Dynein is essential for the formation and positioning of the mitotic spindle as well as the transport of various cargos in the cell.

Cytoplasmic dynein-1 cargo diversity is mediated by the combinatorial assembly of FTS–Hook–FHIP complexes

eLife, 2021
In eukaryotic cells, intracellular components are organized by the microtubule motors cytoplasmic dynein-1 (dynein) and kinesins, which are linked to cargos via adaptor proteins.

Cancer Stem Cells Shift Metabolite Acetyl‐Coenzyme A to Abrogate the Differentiation of CD103+ T Cells

Advanced Science, EarlyView.
Lei et al. demonstrate that cancer stem cells (CSCs) play a pivotal role in impairing the differentiation of CD103+ T cells in patients with non‐small‐cell lung cancer. The key mechanism involves CSC‐derived acetyl‐CoA, which disrupts CD103+ T cell differentiation by sequentially inducing acetylation and ubiquitination of the Blimp‐1 protein. Targeting

Mapping the Non‐Canonical Splicing Variants: Decrypting the Hidden Genetic Architecture of Idiopathic Male Infertility

Advanced Science, EarlyView.
This study highlights the significance of non‐canonical splicing variants in male infertility, a factor often overlooked during the analysis of high‐throughput sequencing data. Incorporating the non‐canonical splicing variants prioritization in the genetic analysis pipeline will increase the genetic diagnosis of patients with male infertility ...

Alu Overexpression Leads to an Increased Double‐Stranded RNA Signature in Dermatomyositis

Arthritis &Rheumatology, EarlyView.
Objective Dermatomyositis is an autoimmune condition characterized by a high interferon signature of unknown etiology. Because coding sequences constitute <1.2% of our genomes, there is a need to explore the role of the noncoding genome in disease pathogenesis.

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.
