The differential extension in dsDNA bound to Rad51 filaments may play important roles in homology recognition and strand exchange [PDF]
RecA and Rad51 proteins play an important role in DNA repair and homologous recombination. For RecA, X-ray structure information and single molecule force experiments have indicated that the differential extension between the complementary strand and its

In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Condensin II subunit dCAP-D3 restricts retrotransposon mobilization in Drosophila somatic cells. [PDF]
Retrotransposon sequences are positioned throughout the genome of almost every eukaryote that has been sequenced. As mobilization of these elements can have detrimental effects on the transcriptional regulation and stability of an organism's genome, most

Homolog pairing during meiosis : dyneins on the move [PDF]
Meiosis is a specialized form of cell division that generates haploid gametes from diploid cells. This is achieved by having 1 round of DNA replication followed by 2 rounds of nuclear division.

Tau acetylation at K331 has limited impact on tau pathology in vivo
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

The onset of homologous chromosome pairing during Drosophila melanogaster embryogenesis. [PDF]
We have determined the position within the nucleus of homologous sites of the histone gene cluster in Drosophila melanogaster using in situ hybridization and high-resolution, three-dimensional wide field fluorescence microscopy.

Evidence that MEK1 positively promotes interhomologue double-strand break repair [PDF]
During meiosis there is an imperative to create sufficient crossovers for homologue segregation. This can be achieved during repair of programmed DNA double-strand breaks (DSBs), which are biased towards using a homologue rather than sister chromatid as ...

SUMMARY The relationship between chromatin organization and transcriptional regulation is an area of intense investigation. We have characterized the spatial relationships between alleles of the Oct4, Sox2, and Nanog genes in single cells during the ...

Calpain small subunit homodimerization is robust and calcium‐independent
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These
