Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

A simplified Solar Radiation Pressure model for GNSS autonomous orbit prediction [PDF]
, 2016 We present a two-parameter Solar Radiation Pressure model for GNSS autonomous orbit prediction, in which the parameters vary with the daily and seasonal variations in the angle between the Sun and the satellite’s orbital plane.

FEBS Letters, EarlyView.Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Quantum depletion and superfluid density of a supersolid in Raman spin-orbit-coupled Bose gases [PDF]
, 2018 We theoretically investigate a three-dimensional weakly interacting Bose gas with one-dimensional Raman-type spin-orbit coupling at zero temperature. By employing an improved ansatz, including high-order harmonics in the stripe phase, we show that the ...

Development of On-orbit Predictions for the Middeck Active Control Experiment
IFAC Proceedings Volumes, 1994 Abstract The modeling and control design issues associated with a change in the operating environment are discussed for the Middeck Active Control Experiment (MACE): a Shuttle program scheduled for flight on STS-67, January 1995. MACE has been designed to investigate the extent to which the on-orbit behavior of flexible spacecraft can be predicted ...
