Tug-of-war between dissimilar teams of microtubule motors regulates transport and fission of endosomes

V Soppina, AK Rai, AJ Ramaiya… - Proceedings of the …, 2009 - National Acad Sciences
Intracellular transport is interspersed with frequent reversals in direction due to the presence
of opposing kinesin and dynein motors on organelles that are carried as cargo. The cause …

[HTML][HTML] Molecular adaptations allow dynein to generate large collective forces inside cells

AK Rai, A Rai, AJ Ramaiya, R Jha, R Mallik - Cell, 2013 - cell.com
Many cellular processes require large forces that are generated collectively by multiple
cytoskeletal motor proteins. Understanding how motors generate force as a team is therefore …

Kinase-controlled phase transition of membraneless organelles in mitosis

AK Rai, JX Chen, M Selbach, L Pelkmans - Nature, 2018 - nature.com
Liquid–liquid phase separation has been shown to underlie the formation and disassembly
of membraneless organelles in cells, but the cellular mechanisms that control this …

[PDF][PDF] Feedback from nuclear RNA on transcription promotes robust RNA concentration homeostasis in human cells

S Berry, M Müller, A Rai, L Pelkmans - Cell Systems, 2022 - cell.com
RNA concentration homeostasis involves coordinating RNA abundance and synthesis rates
with cell size. Here, we study this in human cells by combining genome-wide perturbations …

Teamwork in microtubule motors

R Mallik, AK Rai, P Barak, A Rai, A Kunwar - Trends in cell biology, 2013 - cell.com
Diverse cellular processes are driven by the collective force from multiple motor proteins.
Disease-causing mutations cause aberrant function of motors, but the impact is observed at a …

DYRK3 enables secretory trafficking by maintaining the liquid-like state of ER exit sites

R Gallo, AK Rai, ABR McIntyre, K Meyer, L Pelkmans - Developmental Cell, 2023 - cell.com
The dual-specificity kinase DYRK3 controls the formation and dissolution of multiple biomolecular
condensates, regulating processes including stress recovery and mitotic progression. …

[PDF][PDF] Coin tossing explains the activity of opposing microtubule motors on phagosomes

P Sanghavi, A D'Souza, A Rai, A Rai, R Padinhatheeri… - Current Biology, 2018 - cell.com
How the opposing activity of kinesin and dynein motors generates polarized distribution of
organelles inside cells is poorly understood and hotly debated [1, 2]. Possible explanations …

DYRK3-controlled phase separation organizes the early secretory pathway

R Gallo, A Rai, L Pelkmans - Biorxiv, 2020 - biorxiv.org
The dual-specificity kinase DYRK3 controls formation and dissolution of several intracellular
condensates thereby regulating various cell physiological processes. Here we report that …

[HTML][HTML] Dual specificity kinase DYRK3 regulates cell migration by influencing the stability of protrusions

…, S Surini, K Sala, D Tonoli, JM Cioni, AK Rai… - Iscience, 2024 - cell.com
Plasma membrane-associated platforms (PMAPs) form at specific sites of plasma membrane
by scaffolds including ERC1 and Liprin-α1. We identify a mechanism regulating PMAPs …

Simple non-fluorescent polarity labeling of microtubules for molecular motor assays

V Soppina, AK Rai, R Mallik - Biotechniques, 2009 - Future Science
Transport of intracellular organelles along the microtubule cytoskeleton occurs in a bidirectional
manner due to opposing activity of microtubule-associated motor proteins of the kinesin …
