A small-molecule inhibitor of T. gondii motility induces the posttranslational modification of myosin light chain-1 and inhibits myosin motor activity [PDF]
Toxoplasma gondii is an obligate intracellular parasite that enters cells by a process of active penetration. Host cell penetration and parasite motility are driven by a myosin motor complex consisting of four known proteins: TgMyoA, an unconventional ...

Kinesin-14 : the roots of reversal [PDF]
Kinesin-14 motor proteins step towards microtubule minus ends, in the opposite direction to other kinesins. Work on the still-enigmatic kinesin-14 mechanism published in BMC Structural Biology shows that the carboxyl terminus of the motor head undergoes ...

Amyotrophic lateral sclerosis is the most common adult-onset neurodegenerative disease affecting motor neurons. Its defining feature is progressive loss of motor neuron function in the cortex, brainstem, and spinal cord, leading to paralysis and death ...

An autonomous molecular transport system using DNAs and motor proteins in molecular communication [PDF]
This paper describes a molecular transport system in molecular communication that uses the machinery in living cells. The molecular transport system requires: 1) loading of the specified cargo molecules at a loading site (at a sender); 2) transport of the loaded cargoes to an unloading site (to a receiver); and 3) unloading of the transported cargoes ...

The agrin gene codes for a family of basal lamina proteins that differ in function and distribution [PDF]
We isolated two cDNAs that encode isoforms of agrin, the basal lamina protein that mediates the motor neuron-induced aggregation of acetylcholine receptors on muscle fibers at the neuromuscular junction.

Mitochondrial heat shock protein 70, a molecular chaperone for proteins encoded by mitochondrial DNA [PDF]
Mitochondrial heat shock protein 70 (mt-Hsp70) has been shown to play an important role in facilitating import into, as well as folding and assembly of nuclear-encoded proteins in the mitochondrial matrix.

Structural characterisation of outer membrane proteins from Borrelia burgdorferi sensu lato by small-angle X-ray scattering [PDF]
Forming the interface between the bacterial cell and the host, the outer membrane of Borrelia is known to play a key role in pathogenicity. Although Borrelia burgdorferi sensu lato are considered to be Gram-negative, their outer membrane is unique ...

Molecular motors in nanobiotechnology: Protein and DNA based molecular motors: A review
Molecular motor can be defined as the collection of a separate number of molecular features (that is, a supramolecular structure) which has been developed to carry out a function through the mechanical movements of its components, which occurs when it is appropriately stimulated externally. Therefore, molecular motors include a part with a motor, which

Pathological alterations of the Golgi apparatus, such as its fragmentation represent an early pre-clinical feature of many neurodegenerative diseases and have been widely studied in the motor neuron disease amyotrophic lateral sclerosis (ALS).

Actomyosin organelle functions of SPIRE actin nucleators precede animal evolution
An important question in cell biology is how cytoskeletal proteins evolved and drove the development of novel structures and functions. Here we address the origin of SPIRE actin nucleators.
