Myosin XVA: dancing at the tips of the stereocilia

Journal of Bio-X Research, 2020
. Myosins comprise a large superfamily of adenosine triphosphatases (ATPases) that interact with actin filaments to generate motility or force. Unconventional myosins are implicated in diverse cellular processes including organelle trafficking, F-actin ...

Myosin VI regulates the spatial organisation of mammalian transcription initiation

Nature Communications, 2022
The actin-based molecular motors, myosins, have also been linked to transcription, but their precise role has remained elusive. Here the authors show RNA polymerase II (RNAPII) is lost from chromatin upon myosin perturbation and that myosin acts as a ...

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

FEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Reconstructing the phylogeny of 21 completely sequenced arthropod species based on their motor proteins

BMC Genomics, 2009
Background Motor proteins have extensively been studied in the past and consist of large superfamilies. They are involved in diverse processes like cell division, cellular transport, neuronal transport processes, or muscle contraction, to name a few ...

Early Clinical, Imaging, and Pathological Characteristics of SRPK3/TTN‐Digenic Myopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective SRPK3/TTN‐digenic myopathy was recently established as a skeletal muscle myopathy caused by digenic inheritance. This study characterizes the early clinical presentation of SRPK3/TTN‐digenic myopathy in one previously reported and seven newly identified pediatric patients.

Switch-2 determines Mg2+ADP-release kinetics and fine-tunes the duty ratio of Dictyostelium class-1 myosins

Frontiers in Physiology
Though myosins share a structurally conserved motor domain, single amino acid variations of active site elements, including the P-loop, switch-1 and switch-2, which act as nucleotide sensors, can substantially determine the kinetic signature of a myosin,

Multiple myosin motors interact with sodium/potassium-ATPase alpha 1 subunits

Molecular Brain, 2018
The alpha1 (α1) subunit of the sodium/potassium ATPase (i.e., Na+/K+-ATPase α1), the prototypical sodium pump, is expressed in each eukaryotic cell. They pump out three sodium ions in exchange for two extracellular potassium ions to establish a cellular ...

Extent of myosin penetration within the actin cortex regulates cell surface mechanics

Nature Communications, 2021
Cellular deformations are largely driven by contractile forces generated by myosin motors in the submembraneous actin cortex. Here we show that these forces are controlled not simply by cortical myosin levels, but rather by myosins spatial arrangement ...
