Family‐level specialization in protein domain insertion architectures

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Domain insertion creates architectures where one domain interrupts another's sequence. Analysis across 2.7 million classified domains reveals that insertions occur in 20% of multidomain proteins, with 331 families exhibiting consistent architectural roles: 162 function exclusively as hosts, while 169 exclusively serve as inserted modules, such

Influence of Peptide‐Based Chelator Sequences on HER2‐Targeting Radiopeptide

open access: yesJournal of Peptide Science, Volume 32, Issue 5, May 2026.
Peptide‐based chelator consisting of Cys‐Gly‐Gly‐Gly incorporated into HER2‐targeting rL‐A9 peptide for 99mTc‐labeling. [99mTc]Tc‐CGGG‐rL‐A9 exhibited high binding affinity and tumor uptake and retention. ABSTRACT In our pursuit of developing HER2‐targeting radiolabeled peptides for detection and therapy of HER2‐positive breast cancer, the previously ...

Role of Anharmonicity and Bimetallic Intermixing in the IR and Raman Spectra of Cun$_{n}$ and Pdn$_{n}$Cu6−n$_{6-n}$ Clusters (n<7$n\lt 7$). Ab Initio Benchmarking of DFT

open access: yesSmall Structures, Volume 7, Issue 5, May 2026.
High‐level ab initio and density functional theory calculations reveal a structural and spectroscopic transition from pla nar Cu6 to three‐dimensional Pd6, whose lowest energy triplet state undergoes a Jahn‐Teller distortion. This evolution from molecule‐like to metal‐like bonding produces distinct infrared and Raman fingerprints, providing reliable ...

Structures of variants of Escherichia coli flavodiiron‐type nitric oxide reductase reveal changes in the di‐iron site

open access: yesActa Crystallographica Section D, Volume 82, Issue 5, Page 457-470, May 2026.
Flavodiiron proteins (FDPs) are di‐iron enzymes that reduce NO and/or O2 with distinct substrate selectivity. We have produced E. coli FDP variants targeting second coordination‐sphere residues and determined their structures. Although the kinetics remained unchanged, the E.

Alphafuser: a parsimonious approach to predicting higher‐order protein complexes

open access: yesActa Crystallographica Section D, Volume 82, Issue 5, Page 421-433, May 2026.
Alphafuser is a structure‐prediction pipeline that integrates experimental interaction data with AlphaFold‐based modeling to systematically assemble multiprotein complexes in a computationally efficient manner. By implementing an ipTM‐based pruning algorithm and validating against known structures and experimental assays, Alphafuser enables the ...

Transition From Land to Sea: Comparative Genomics Illuminates the Adaptive Evolution of the Intertidal Spider

open access: yesMolecular Ecology Resources, Volume 26, Issue 4, May 2026.
ABSTRACT Spiders are renowned for their ecological versatility and silk‐based innovations in materials science, yet marine environments remain virtually uncolonized by this predominantly terrestrial lineage. A striking exception is the obligate intertidal spider genus Desis, whose members have evolved extraordinary physiological and behavioural ...

Molecular basis for a pore block of Tentonin 3 expressed in HEK293 cells by a conopeptide, NMB‐1

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 9, Page 1845-1859, May 2026.
Background and Purpose Tentonin 3 (TTN3/TMEM150C) is a mechanosensitive ion channel that plays critical roles in mechanotransduction processes. TTN3 forms a tetramer with a predicted rectangular shape and a central pore. A conotoxin ρ‐TIA and its synthetic analog, noxious mechanosensation blocker 1 (NMB‐1), were initially developed to inhibit slowly ...
