SherLoc2 is a comprehensive high-accuracy subcellular localization prediction system. It is applicable to animal, fungal, and plant proteins and covers all main eukaryotic subcellular locations. SherLoc2 integrates several sequence-based features as well as text-based features. In addition, we incorporate phylogenetic profiles and Gene Ontology (GO) terms derived from the protein sequence to considerably improve the prediction performance. SherLoc2 achieves an overall classification accuracy of up to 93% in 5-fold cross-validation. A novel feature, DiaLoc, allows users to manually provide their current background knowledge by describing a protein in a short abstract which is then used to improve the prediction. SherLoc2 is available both as a free Web service and as a stand-alone version at http://www-bs.informatik.uni-tuebingen.de/Services/SherLoc2.

Antibody (Ab) crosslinking of HLA class II (HLA II) molecules on the surface of endothelial cells (ECs) triggers proliferative and prosurvival intracellular signaling, which are implicated in promoting chronic Ab-mediated rejection (cAMR). Despite the importance of cAMR in transplant medicine, the mechanisms involved remain incompletely understood. Here, we examined the regulation of yes-associated protein (YAP) nuclear cytoplasmic localization and phosphorylation in human ECs challenged with Abs that bind HLA II, which are strongly associated with cAMR.

Under salt stress, plasma membrane proteins regulate ion homeostasis and the balance between reactive oxygen species (ROS). In this study, we investigated the functions of two small membrane proteins-MsRCI2B (tailless) and MsRCI2E (tailed)-encoded by the RCI2 (Rare Cold Inducible 2) gene family in Medicago sativa (alfalfa). We identified the distinct subcellular localization and expression patterns of these proteins under salt stress.

Nitric oxide (NO) has been highlighted as a key gaseous signaling molecule in the body, playing a central role in various physiological and pathological processes. However, a comprehensive analysis of NO metabolism dynamics in living cells remains a significant challenge. To address this, we have developed and characterized a novel genetically encoded NO fluorescence sensor, GefiNO, to investigate NO metabolism dynamics in living cells and subcellular organelles.

DEHP is a prevalent phthalate with wide industrial applications and well-documented endocrine-disrupting effects, including the potential disruption of AR signaling in different tissues. The present study aimed to investigate the effects of gestational and lactational exposure to environmentally relevant DEHP concentrations on AR expression and subcellular localization in the pituitary gland, the master endocrine organ, with a focus on gonadotroph cells by in vivo and in vitro approaches. After DEHP exposure during gestation and lactation, a sex-specific modulation was detected in AR-positive pituitary cells and AR protein expression as assessed through flow cytometry and western blot.
