In developing hippocampal neurons in culture, the evolutionarily conserved polarity complex mPar3/mPar6/aPKC selectively accumulates at the tip of one, and only one, of the immature neurites of a neuron and thus specifies the axon and generates neuronal polarity. How mPar3/mPar6 is enriched at the tip of the nascent axon, but not the dendrites, is not fully(More)
Calcium-activated chloride channels (CaCCs) are major regulators of sensory transduction, epithelial secretion, and smooth muscle contraction. Other crucial roles of CaCCs include action potential generation in Characean algae and prevention of polyspermia in frog egg membrane. None of the known molecular candidates share properties characteristic of most(More)
Collapse of membrane lipid asymmetry is a hallmark of blood coagulation. TMEM16F of the TMEM16 family that includes TMEM16A/B Ca(2+)-activated Cl(-) channels (CaCCs) is linked to Scott syndrome with deficient Ca(2+)-dependent lipid scrambling. We generated TMEM16F knockout mice that exhibit bleeding defects and protection in an arterial thrombosis model(More)
TMEM16A forms calcium-activated chloride channels (CaCCs) that regulate physiological processes such as the secretions of airway epithelia and exocrine glands, the contraction of smooth muscles, and the excitability of neurons. Notwithstanding intense interest in the mechanism behind TMEM16A-CaCC calcium-dependent gating, comprehensive surveys to identify(More)
In the developing mammalian brain, a large fraction of excitatory synapses initially contain only N-methyl-D-aspartate receptor and thus are "silent" at the resting membrane potential. As development progresses, synapses acquire alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPA-Rs). Although this maturation of excitatory synapses has(More)
How metazoan mechanotransduction channels sense mechanical stimuli is not well understood. The NOMPC channel in the transient receptor potential (TRP) family, a mechanotransduction channel for Drosophila touch sensation and hearing, contains 29 Ankyrin repeats (ARs) that associate with microtubules. These ARs have been postulated to act as a tether that(More)
Mechanisms governing a neuron's regenerative ability are important but not well understood. We identify Rtca (RNA 3'-terminal phosphate cyclase) as an inhibitor of axon regeneration. Removal of Rtca cell-autonomously enhanced axon regrowth in the Drosophila CNS, whereas its overexpression reduced axon regeneration in the periphery. Rtca along with the RNA(More)
In this paper, the system of Chinese chess robot is demonstrated, and it presents the latest development of artificial intelligence. The robot could play Chinese chess with human autonomously - with “eyes” it can recognize the pieces on the chessboard and move them with its mechanical arm. Furthermore, it has high intelligence which could(More)
To facilitate the development of intelligent robots, a virtual entity based rapid prototype developing framework (VE-RPDF) is proposed. It aims at helping design intelligent robots through the following steps: rapidly setting up a robot prototype, coding for the control strategy and algorithm, and optimizing the robot design by testing it on both virtual(More)
Drosophila larval locomotion, which entails rhythmic body contractions, is controlled by sensory feedback from proprioceptors. The molecular mechanisms mediating this feedback are little understood. By using genetic knock-in and immunostaining, we found that the Drosophila melanogaster transmembrane channel-like (tmc) gene is expressed in the larval class I(More)
