Structure of a molluscan cardioexcitatory neuropeptide.
A cardioexcitatory substance from ganglia of the clam Macrocallista nimbosa, formerly designated peak C, is the tetrapeptide amide Phe-Met-Arg-Phe-NH2. Its structure was determined by the combinedExpand
Osmoregulation and salinity tolerance in two species of bivalve mollusc: Limnoperna fortunei and Mytilopsis leucophaeta
This paper reports on salinity tolerance and osmotic regulation in two bivalve molluscs: Mytilopsis leucophaeta Conrad, an oligohaline species (subclass Heterodonta) and Limnoperna fortunei Dunker, aExpand
Myosin IC generates power over a range of loads via a new tension-sensing mechanism
Myosin IC (myo1c), a widely expressed motor protein that links the actin cytoskeleton to cell membranes, has been associated with numerous cellular processes, including insulin-stimulated transportExpand
Characterization of Two Novel Neuropeptides From the Sea Cucumber Holothuria glaberrima.
Two peptides were purified from intestinal extracts of a sea cucumber, Holothuria glaberrima, by high pressure liquid chromatography (HPLC). The peptides were detected by a radioimmunoassay (RIA)Expand
Regulation and control of myosin-I by the motor and light chain-binding domains.
Members of the myosin-I family of molecular motors are expressed in many eukaryotes, where they are involved in a multitude of critical processes. Humans express eight distinct members of theExpand
There is no horohalinicum
Species abundance declines to a minimum (the Artenminimum) between 5 and 8‰, not only in estuaries, but in all bodies of brackish water. Khlebovich (1968) examined published hydrochemical data forExpand
Positive cardiac inotrope omecamtiv mecarbil activates muscle despite suppressing the myosin working stroke
Omecamtiv mecarbil (OM) is a positive cardiac inotrope in phase-3 clinical trials for treatment of heart failure. Although initially described as a direct myosin activator, subsequent studies are atExpand
Chapter 3 Relationships among the FMRFamide-like peptides
Publisher Summary More than a hundred FMRFamide-related peptides (FARPs) from most of the major phyla have been identified by their binding to FMRFamide antisera, by their actions on FMRFamideExpand
Visceral regeneration in holothurians
Holothurians, or sea cucumbers, exhibit two processes that have intrigued biologists for decades: autotomy and regeneration. Autotomy includes the loss of body parts by evisceration or fission, andExpand
The direct molecular effects of fatigue and myosin regulatory light chain phosphorylation on the actomyosin contractile apparatus.
Skeletal muscle, during periods of exertion, experiences several different fatigue-based changes in contractility, including reductions in force, velocity, power output, and energy usage. TheExpand
