The N-myc proto-oncogene is expressed in many organs of the mouse embryo, suggesting that it has multiple functions. A null mutation leads to mid-gestation lethality [1-4], obscuring the later roles of the gene in organogenesis. We have generated a multi-purpose gene alteration by combining the potential for homologous and site-specific recombination in a(More)
Myosin V is a single-molecule motor that moves organelles along actin. When myosin V pulls loads inside the cell in a highly viscous environment, the force on the motor is unlikely to be constant. We propose that the tether between the single-molecule motor and the cargo (i.e., the extended tail domain of the molecule) must be able to absorb the sudden(More)
The actin cytoskeleton carries out cellular functions, including division, migration, adhesion, and intracellular transport, that require a variety of actin binding proteins, including myosins. Our focus here is on class II nonmuscle myosin isoforms, NMIIA, NMIIB, and NMIIC, and their regulation by the actin binding protein, tropomyosin. NMII myosins are(More)
The gene encoding Drosophila myosin-18 is complex and can potentially yield six alternatively spliced mRNAs. One of the major features of this myosin is an N-terminal PDZ domain that is included in some of the predicted alternatively spliced products. To explore the biochemical properties of this protein, we engineered two minimal motor domain (MMD)-like(More)
In quantum computation we are given a finite set of gates and we have to perform a desired operation as a product of them. The corresponding computational problem is approximating an arbitrary unitary as a product in a topological generating set of SU (d). The problem is known to be solvable in time polylog(1/ǫ) with product length polylog(1/ǫ), where the(More)
Class-18 myosins are most closely related to conventional class-2 nonmuscle myosins (NM2). Surprisingly, the purified head domains of Drosophila, mouse, and human myosin 18A (M18A) lack actin-activated ATPase activity and the ability to translocate actin filaments, suggesting that the functions of M18A in vivo do not depend on intrinsic motor activity. M18A(More)
Ralstonia insidiosa is an opportunistic pathogen and a strong biofilm producer. Here, we present the complete genome sequences of R. insidiosa FC1138 and ATCC 49129. Both strains have two circular chromosomes of approximately 3.9 and 1.9 Mb and a 50-kb plasmid. ATCC 49129 also possesses a megaplasmid of approximately 318 kb.
