Meiotic Chromosome Analysis of the Giant Water Bug, Lethocerus indicus
The giant water bug, Lethocerus indicus (Lepeletier and Serville) (Heteroptera: Belostomatidae), a native species of Southeast Asia, is one of the largest insects belonging to suborder Heteroptera. In this study, the meiotic chromosome of L. indicus was studied in insect samples collected from Thailand, Myanmar, Loas, and Cambodia. Testicular cells stained with lacto-acetic orcein, Giemsa, DAPI...
متن کاملStructure of myosin filaments from relaxed Lethocerus flight muscle by cryo-EM at 6 Å resolution
We describe a cryo-electron microscopy three-dimensional image reconstruction of relaxed myosin II-containing thick filaments from the flight muscle of the giant water bug Lethocerus indicus. The relaxed thick filament structure is a key element of muscle physiology because it facilitates the reextension process following contraction. Conversely, the myosin heads must disrupt their relaxed arra...
متن کاملA myosin for RNA Pol II
A myosin for RNA Pol II T ranscription gets a boost from myosin VI, according to fi ndings from Sarah Vreugde (DIBIT Scientifi c Institute, Milano, Italy) and colleagues. The motor might drag genes into transcription neighborhoods. While trying to understand the function of myosin VI, Vreugde noticed that its localization pattern looked much like that of RNA polymerase II. The authors then show...
متن کاملAblation of Nonmuscle Myosin II-B and II-C Reveals a Role for Nonmuscle Myosin II in Cardiac Myocyte Karyokinesis
Ablation of nonmuscle myosin (NM) II-A or NM II-B results in mouse embryonic lethality. Here, we report the results of ablating NM II-C as well as NM II-C/II-B together in mice. NM II-C ablated mice survive to adulthood and show no obvious defects compared with wild-type littermates. However, ablation of NM II-C in mice expressing only 12% of wild-type amounts of NM II-B results in a marked inc...
متن کاملDictyostelium discoideum myosin II: characterization of functional myosin motor fragments.
The transient kinetic properties of the recombinant myosin head fragments M761 and M781, which both lack the light chain binding domain (LCBD) and correspond to the first 761 and 781 residues of Dictyostelium discoideum myosin II, were compared with those of the subfragment 1-like fragment M864 and a shorter catalytic domain fragment M754. The properties of M761, M781, and M864 are almost ident...
