Extracellular and Membrane Protein: Structure, Biological Functions, Diseases, and an Emerging Modality for Drug Discovery

MedComm, Volume 7, Issue 4, April 2026.
Targeted protein degradation represents a paradigm shift from traditional protein inhibition to complete protein elimination. This is achieved through three main strategies for degrading extracellular and membrane proteins: recruitment of cell‐surface LTRs, engagement of intracellular proteins, and receptor‐independent mechanisms.

ApoJ regulates endothelial lipase activity and stability

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Endothelial lipase (EL) is a key regulator of high‐density lipoprotein (HDL) metabolism. Many aspects of EL function remain incompletely understood due to challenges in purifying active EL. This study identifies apolipoprotein J (ApoJ) as a novel chaperone for EL, crucial for its solubility and activity.

Toxic mechanisms of amyloid oligomers and therapeutic strategies

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Amyloid oligomers are increasingly recognized as the major toxic contributors across protein‐misfolding disorders. In this review, we cover mechanistic evidence showing how these transient and structurally heterogeneous oligomers disrupt cellular homeostasis by: (i) permeabilizing lipid membranes and forming ion‐conducting pores; (ii ...

Structural and morphological dynamics of “on‐path” and “off‐path” oligomers of human islet amyloid polypeptide

Protein Science, Volume 35, Issue 4, April 2026.
Abstract The deposition of cytotoxic human islet amyloid polypeptide (IAPP) aggregates is a hallmark feature of Type 2 Diabetes. However, the structural evolution and cytotoxicity of IAPP aggregate species remain poorly understood. This study combines kinetics, biophysical and cell assays to resolve the morphological dynamics of IAPP aggregation. Using

In vitro, cellular and in vivo studies of amyloid oligomers structure and toxicity: Challenges and advances

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Oligomeric assemblies of amyloidogenic proteins, such as Aβ, tau, α‐synuclein, amylin, transthyretin, and TDP‐43, are increasingly recognized as key drivers of cellular dysfunction across a range of neurodegenerative and systemic disorders.
