20080300207 | PROTEIN PRODUCTION - The invention concerns the field of protein production and cell culture technology. CERT is identified as a novel in vivo PKD substrate. Phosphorylation on serine 132 by PKD decreases the affinity of CERT towards its lipid target phosphatidylinositol 4-phosphate at Golgi membranes and reduces ceramide transfer activity, identifying PKD as a regulator of lipid homeostasis. The present invention shows that CERT in turn is critical for PKD activation and PKD dependent protein cargo transport to the plasma membrane. The interdependence of PKD and CERT is thus a key to the maintenance of Golgi membrane integrity and secretory transport. | 12-04-2008 |

20090243677 | Clock generator and methods using closed loop duty cycle correction - Closed-loop duty-cycle correctors (DCCs), clock generators, memory devices, systems, and methods for generating an output clock signal having a particular duty cycle are provided, such as clock generators configured to generate an output clock signal synchronized with a received input clock signal having a predetermined duty cycle. Embodiments of clock generators include closed-loop duty cycle correctors that receive an already-controlled and corrected output signal. For example, DLL control circuitry and DCC control circuitry may each adjust a delay of a variable delay line. The DLL control circuitry adjusts the delay such that an output clock signal is synchronized with an input clock signal. The DCC control circuitry detects a duty cycle error in the output clock signal and adjusts the delay of the variable delay line to achieve a duty cycle corrected output signal. By detecting the duty cycle error in the output signal, the clock generator may achieve improved performance that can correct accumulated duty cycle error and correct for duty cycle error introduced by the duty cycle corrector itself in some embodiments. | 10-01-2009 |
20090315600 | LOCKED-LOOP QUIESCENCE APPARATUS, SYSTEMS, AND METHODS - Apparatus, systems, and methods disclosed herein may initialize a delay-locked loop (DLL) or phase-locked loop (PLL) to achieve a locked condition and may then initiate a quiescent mode of operation. Quiescent operation may be achieved by breaking a feedback loop associated with the DLL or PLL to prevent updates to a variable delay line associated with the DLL and/or to a variable frequency oscillator associated with the PLL. An output clock phase associated with the DLL or PLL may thus be held substantially constant following a DLL initialization period. Additional embodiments are disclosed and claimed. | 12-24-2009 |
