  • APPARATUSES AND METHODS FOR TRANSMITTING AN OPERATION MODE WITH A CLOCK
    Publication number: 20200287547
    Abstract: Apparatuses and methods for transmitting a command mode (e.g., operation mode) associated with a command between devices are disclosed. One device may be configured as a master and one or more devices may be configured as slaves. The command mode may be transmitted by the master to the slaves by setting a resting state of a clock signal transmitted between the devices and transitioning a device enable signal to an active state. The slaves may detect the resting state of the clock at the time the enable signal is transitioned to the active state in order to determine the command mode of the command. The devices may then execute the command in the mode indicated by the transmitted command mode.

  • METHOD FOR REGULATING TARGETING OF NOVEL SYNAPTIC PROTEIN, CCNY PROTEIN, TO SYNAPSES
    Publication number: 20200140507
    Abstract: The present invention relates to a method for regulating localization of CCNY protein to synapses, comprising palmitoylation of CCNY protein. Specifically, the present invention relates to a method for regulating targeting of CCNY protein to synapses by regulating addition of a palmitoyl group to cysteine at position 7 and/or 8 on the CCNY protein. Therefore, the palmitoylation of CCNY, a postsynaptic protein known to be implicated in synaptic plasticity and learning and memory, is a critical process for CCNY to be localized in postsynaptic spines, and thus it can be found that CCNY plays an important role in synaptic functions.
