A BAG-1-inhibitory peptide, GO-Pep, suppresses c-Raf activity in cancer.

BAG-1 interacts with multiple partners, particularly with c-Raf, and promotes cancer cell survival. Hence, modulating the BAG-1-associated interactions with novel inhibitors could provide benefit for cancer therapy. Using HDX-MS, we first demonstrate the higher-order structure of BAG-1S and identify a potential "druggable" site on its BAG domain.

AlphaML: A clear, legible, explainable, transparent, and elucidative binary classification platform for tabular data.

Leveraging the potential of machine learning and recognizing the broad applications of binary classification, it becomes essential to develop platforms that are not only powerful but also transparent, interpretable, and user friendly. We introduce alphaML, a user-friendly platform that provides clear, legible, explainable, transparent, and elucidative (CLETE) binary classification models with comprehensive customization options. AlphaML offers feature selection, hyperparameter search, sampling, and normalization methods, along with 15 machine learning algorithms with global and local interpretation.

A two-step purification platform for efficient removal of Fab-related impurities: A case study for Ranibizumab.

Antibodies (mAbs) and antibody fragments (Fabs) constitute one of the largest and most rapidly expanding groups of protein pharmaceuticals. In particular, antibody fragments have certain advantages over mAbs in some therapeutic settings. However, due to their greater chemical diversity, they are more challenging to purify for large-scale production using a standard purification platform.

Recent Developments in Targeting RAS Downstream Effectors for RAS-Driven Cancer Therapy.

Aberrant activity of oncogenic rat sarcoma virus (RAS) protein promotes tumor growth and progression. RAS-driven cancers comprise more than 30% of all human cancers and are refractory to frontline treatment strategies. Since direct targeting of RAS has proven challenging, efforts have been centered on the exploration of inhibitors for RAS downstream effector kinases.

Interactome analysis of Bag-1 isoforms reveals novel interaction partners in endoplasmic reticulum-associated degradation.

Bag-1 is a multifunctional protein that regulates Hsp70 chaperone activity, apoptosis, and proliferation. The three major Bag-1 isoforms have different subcellular localizations and partly non-overlapping functions. To identify the detailed interaction network of each isoform, we utilized mass spectrometry-based proteomics and found that interactomes of Bag-1 isoforms contained many common proteins, with variations in their abundances.

Seroprevalence of coronavirus disease 2019 (COVID-19) among health care workers from three pandemic hospitals of Turkey.

COVID-19 is a global threat with an increasing number of infections. Research on IgG seroprevalence among health care workers (HCWs) is needed to re-evaluate health policies. This study was performed in three pandemic hospitals in Istanbul and Kocaeli.

Co-Chaperone Bag-1 Plays a Role in the Autophagy-Dependent Cell Survival through Beclin 1 Interaction.

Expression levels of the major mammalian autophagy regulator Beclin 1 and its interaction with Bcl-2 regulate the switch between autophagic cell survival and apoptotic cell death pathways. However, some of the regulators and the precise mechanisms of these processes still remain elusive. Bag-1 (Bcl-2 associated athanogene-1), a member of BAG family proteins, is a multifunctional pro-survival molecule that possesses critical functions in vital cellular pathways.

Hyperthermophilic flavin reductase from Sulfolobus solfataricus P2: Production and biochemical characterization.

Nicotinamide adenine dinucleotide phosphate (NAD(P)H)-flavin oxidoreductases (flavin reductases) catalyze the reduction of flavin by NAD(P)H and provide the reduced form of flavin mononucleotide (FMN) to flavin-dependent monooxygenases. Based on bioinformatics analysis, we identified a putative flavin reductase gene, sso2055, in the genome of hyperthermophilic archaeon Sulfolobus solfataricus P2, and further cloned this target sequence into an expression vector. The cloned flavin reductase (EC.

Time-dependent leaf proteome alterations of Brachypodium distachyon in response to drought stress.

For the first time, a comprehensive proteome analysis was conducted on Brachypodium leaves under drought stress. Gradual changes in response to drought stress were monitored. Drought is one of the major stress factors that dramatically affect the agricultural productivity worldwide.
