Abstract The membrane attack complex (MAC)/perforin-like protein complement component 9 (C9) is the major of MAC, a multi-protein that forms pores in target pathogens. In contrast to homologous proteins such as perforin and cholesterol-dependent cytolysins (CDCs), all which require for oligomerisation, C9 assembles directly onto nascent MAC from solution. However, molecular mechanism assembly remains be understood. Here we present 8 Å cryo-EM structure soluble form poly-C9 MAC. These data...

Abstract Macrophage-expressed gene 1 (MPEG1/Perforin-2) is a perforin-like protein that functions within the phagolysosome to damage engulfed microbes. MPEG1 thought form pores in target membranes, however, its mode of action remains unknown. We use cryo-Electron Microscopy (cryo-EM) determine 2.4 Å structure hexadecameric assembly displays expected features soluble prepore complex. further discover prepore-like assemblies can be induced perforate membranes through acidification, such as...

Tumor-associated peptide–human leukocyte antigen complexes (pHLAs) represent the largest pool of cell surface–expressed cancer-specific epitopes, making them attractive targets for cancer therapies. Soluble bispecific molecules that incorporate an anti-CD3 effector function are being developed to redirect T cells against these using 2 different approaches. The first achieves pHLA recognition via affinity-enhanced versions natural TCRs (e.g., immune-mobilizing monoclonal receptors [ImmTAC]...

Abstract Complement component 9 (C9) functions as the pore-forming of Membrane Attack Complex (MAC). During MAC assembly, multiple copies C9 are sequentially recruited to membrane associated C5b8 form a pore. Here we determined 2.2 Å crystal structure monomeric murine and 3.9 resolution cryo EM in polymeric assembly. Comparison with other proteins reveals that first transmembrane region (TMH1) is uniquely positioned inhibit its self-assembly absence C5b8. We further show following...

Dysregulation of the inflammatory response underlies numerous diseases. Although most interleukin-1 family cytokines are proinflammatory, human interleukin-37 (IL-37) is a powerful, broad-spectrum inhibitor inflammation and immunity. We determined crystal structure IL-37 to establish anti-inflammatory mechanism this key cytokine in view developing IL-37-based therapies. found that two β-trefoil fold molecules form head-to-head dimer stable solution. variants mutated convert into an obligate...

Abstract The muscular dystrophies encompass a broad range of pathologies with varied clinical outcomes. In the case patients carrying defects in fukutin-related protein (FKRP), these diverse arise from mutations within same gene. This is surprising as FKRP glycosyltransferase, whose only identified function to transfer ribitol-5-phosphate α-dystroglycan (α-DG). Although this modification critical for extracellular matrix attachment, α-DG’s glycosylation status relates poorly disease...

BACKGROUND Acute porphyrias arise from genetic defects in heme synthesis. Significant increases urine porphobilinogen (PBG) levels are diagnostic, enabling further testing and the commencement of targeted therapies. We report a rare case an elderly woman with delayed diagnosis acute variegate porphyria (VP) neurovisceral crisis, anuria, multiorgan failure precipitated by methicillin-sensitive Staphylococcus aureus (MSSA) sepsis. Diagnostic therapeutic difficulties confirming VP crisis anuric...

The zymogen protease plasminogen and its active form plasmin perform key roles in blood clot dissolution, tissue remodeling, cell migration, bacterial pathogenesis. Dysregulation of the plasminogen/plasmin system results life-threatening hemorrhagic disorders or thrombotic vascular occlusion. Accordingly, inhibitors this are clinically important. Currently, tranexamic acid (TXA), a molecule that prevents activation through blocking recruitment to target substrates, is most widely used...

The favorable biophysical attributes of non-antibody scaffolds make them attractive alternatives to monoclonal antibodies. However, due the well-known stability-function trade-off, these gains tend be marginal after functional selection. A notable example is fibronectin Type III (FN3) domain, FNfn10, which has been previously evolved bind lysozyme with 1 pM affinity (FNfn10-α-lys), but suffers from poor thermodynamic and kinetic stability. To explore this compromise further, we grafted...
