Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations
FEBS Letters, EarlyView.The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Refined Measures of Dynamic Connectedness based on TVP-VAR [PDF]
, 2017 In this study, we propose refined measures of dynamic connectedness based on a TVP-VAR approach, that overcomes certain shortcomings of the connectedness measures introduced originally by Diebold and Yilmaz (2009, 2012, 2014).

Time-Varying General Dynamic Factor Models and the Measurement of Financial Connectedness [PDF]
, 2021 We propose a new time-varying Generalized Dynamic Factor Model for high-dimensional, locally stationary time series. Estimation is based on dynamic principal component analysis jointly with singular VAR estimation, and extends to the locally stationary ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
FEBS Letters, EarlyView.This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

International Journal of Global Economics and ManagementThis study investigates the connectedness of two key green bond markets: the Shanghai Stock Exchange Green Bond Index (SSEGB) in China and the S&P U.S. Municipal Green Bond Index (SPMGB) in the United States. Using an R2 decomposed connectedness approach, we analyze the distinct dynamics between these indices.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
