Muscle atrophy through thick but not thin

... in a specific order. The researchers hypothesize that removal of certain thick filament components first permits subsequent MuRF1 access to the myosin heavy chain. However, MuRF1 doesn't exert the same power over the thin filament, which began to come apart even when MuRF1 was absent. "Up to now, ...

Discovery of agile molecular motors could aid in treating motor neuron diseases

... found that a "local delivery" motor, termed myosin V, moves cargo with a variable path short ... track called actin. This flexibility could help myosin V navigate crowded regions of the cell where the ... pose an impediment to motion. Defects in myosin V function also result in neurological defects. ...

A new way of looking at molecular motors

All complex organisms use myosin and its relatives, kinesin and dynein, to move ... includes 250 myosins and increases the number of myosin subclasses from 18 to 24, enabling researchers to ... compound adenosine triphosphate (ATP) for fuel. myosin runs on the filaments of actin, a protein found ...

Movement of chromosome in nucleus visualized

... biophysics at UIC, who had discovered a type of myosin in the nucleus. Most myosin molecules are found in the cytoplasm, where they ... When the researchers introduced a mutant form of myosin protein to the nucleus, the movement slowed. ...

A new focus for the mechanism of nerve growth

... This study implicates the molecular motor, myosin II, as a key part of the process of recycling the ... and directing nerve growth. Proteins in the myosin family function as molecular motors; the most ... power contraction in heart and skeletal muscles. myosin II motors are involved in functions such as ...

Image of myosin-actin interaction revealed in cover story of Molecular Cell

... atomic-resolution images of the motor protein myosin V as it "walks" along other proteins, revealing ... was the first to reveal the 3D representation of myosin V "walking" along actin filament, a key protein ... electron-cryo microscopy to take 3D snapshots of myosin V and actin interacting, researchers were able to ...

Spiders help scientists discover how muscles relax

... another muscle protein, actin. When the actin and myosin filaments slide along one another, the muscle ... Padron's study focused on the long, rod-shaped myosin of the thick filaments. The heads of these myosin rods project outward from the thick filament to ...

UI researcher studies deafness in fruit flies, humans

... work -- showing that loss of function in the myosin VIIA gene leads to complete deafness in fruit ... component specialized for hearing function, myosin VIIA, is conserved in these ears. In looking ... by the normal flies to those generated by myosin VIIA mutant flies, they showed that ...

Newts which regrow their hearts

... their characteristic properties; they can dedifferentiate. The researchers were able to show that proteins typical of heart muscle cells - the heavy myosin chain and various troponins - were dramatically down-regulated in this process. At the same time, the cells embark on massive cell division to build ...

Python a 'hearty' eater

... aerobic training," said Hicks. In the snake, the rapid ventricular growth coincided with an increased production of the muscle protein, myosin. myosin is involved in muscle contraction, and hence, plays a key role in pumping blood. Hicks and his colleagues propose that these animals could be an ...

DNA Recombination and Repair—A New Twist to RecA Function

... motors harness the energy of ATP (or GTP, a related energy currency) and transform it into mechanical force. Well-known examples of motors include myosin and dynein, proteins that use ATP to ferry intracellular cargo along fibers made of actin or tubulin proteins. The ATP-dependent assembly of actin or ...
