Pirin Transcriptionally Regulates PLA2G4A To Inhibit Ferroptosis in Colorectal Cancer via Lipid Profile Remodeling

open access: yesAdvanced Science, EarlyView.
This study identifies Pirin (PIR), an iron‐binding protein, as a critical ferroptosis suppressor in colorectal cancer through lipid membrane remodeling. PIR, induced by NRF2 during ferroptotic stress, transcriptionally regulates PLA2G4A to shift cellular lipid composition away from ferroptosis‐permissive polyunsaturated phospholipids.

Clathrin structure characterized with monoclonal antibodies. I. Analysis of multiple antigenic sites. [PDF]

open access: yes, 1985
Three monoclonal antibodies that react with previously undefined antigenic determinants on the clathrin molecule have been produced and characterized. They were isolated from a fusion between myeloma cells and popliteal lymphocytes from SJL mice that had

IgG‐Bridging–Seeded Synergistic Aggregation of SARS‐CoV‐2 Spikes Underlies Potent Neutralization by a Low‐Affinity Antibody

open access: yesAdvanced Science, EarlyView.
Low‐affinity antibodies are frequently disregarded in discovery pipelines. This work reports P5‐1C8, a Class 1 SARS‐CoV‐2 antibody with weak trimer binding (KD‐to‐IC50 > 3700‐fold) yet potent neutralization of Omicron JN.1. Structural, biophysical, functional, and coarse‐grained simulations collectively demonstrate that transient inter‐spike IgG ...

Ion exchange chromatography – basic principles and application [PDF]

open access: yes, 2011
Ion-Exchange Chromatography (IEC) allows for the separation of ionizable molecules on the basis of differences in charge properties. Its large sample-handling capacity, broad applicability (particularly to proteins and enzymes), moderate cost, powerful ...

Cryo‐EM Structures Reveal the Molecular Basis of Asymmetric Allosteric Activation by MMOB in the Hydroxylase of Soluble Methane Monooxygenase

open access: yesAdvanced Science, EarlyView.
Cryo‐EM analysis reveals an asymmetric MMOH–MMOB complex with distinct protomers, where MMOB binding triggers structural rearrangements from the surface to the active site. This conformational asymmetry shortens the Fe···Fe distance to 2.7 Å in one protomer, forming a geometry suitable for O2 activation and supporting a sequential catalytic mechanism ...

Cyclosporin A-binding protein (cyclophilin) of Neurospora crassa [PDF]

open access: yes, 1988
Cyclophilin (cyclosporin A-binding protein) has a dual localization in the mitochondria and in the cytosol of Neurospora crassa. The two forms are encoded by a single gene which is transcribed into mRNAs having different lengths and 5' termini ...

A Reactive Antagonist Strategy: Cysteine‐Directed Covalent Molecular Glue in Plant Hormone Receptor Regulation

open access: yesAdvanced Science, EarlyView.
The plant hormone jasmonate is perceived by COI1‐JAZ co‐receptors comprising a single F‐box protein COI1 and multiple JAZ repressors with overlapping functions, complicating genetic analysis. We present a reactive antagonist (RA) strategy that selectively promotes COI1 binding to a cysteine‐engineered JAZ variant while blocking wild‐type JAZs, enabling

IgE clonality and aggregation of insulin affect IgE-mediated activation of sensitized basophils

open access: yesJournal of Allergy and Clinical Immunology: Global
Background: Skin prick testing and specific IgE determination do not discriminate between sensitization and clinically relevant insulin allergic reactions, whereas the basophil histamine release assay has proven useful in identifying clinically relevant ...
