Article Abstract
Preeclampsia is a common multifactorial disease of pregnancy. Dysregulation of complement activation is among emerging candidates responsible for disease pathogenesis. In a targeted exomic sequencing study of 609 women with preeclampsia and 2092 non-preeclamptic controls, we identified 14 variants within nine genes coding for components of the membrane attack complex (MAC, C5b-9) that are associated with preeclampsia. We found two rare missense variants in the C5 gene that predispose to preeclampsia (rs200674959: I1296V, OR (CI95) = 24.13 (1.25-467.43), p value = 0.01 and rs147430470: I330T, OR (CI95) = 22.75 (1.17-440.78), p value = 0.01). In addition, one predisposing rare variant and one protective rare variant were discovered in C6 (rs41271067: D396G, OR (CI95) = 2.93 (1.18-7.10), p value = 0.01 and rs114609505: T190I, 0.02 OR (CI95) = 0.47 (0.22-0.92), p value = 0.02). The results suggest that variants in the terminal complement pathway predispose to preeclampsia.

A Conserved Cia1-Cia2 Interface Mediates Client Recruitment in the Cytosolic Iron-Sulfur Cluster Assembly Pathway.

The cytosolic iron-sulfur cluster assembly (CIA) targeting complex maturates over 30 cytosolic and nuclear Fe-S proteins, raising the question of how a single complex recognizes such a diverse set of clients. The discovery of a C-terminal targeting complex recognition (TCR) peptide in up to 25% of CIA clients provided a clue to substrate specificity, yet the molecular and energetic basis for this interaction remained unresolved. By integrating computational and biochemical approaches, we show that the TCR peptide binds a conserved interface between the Cia1 and Cia2 subunits of the targeting complex, even in the absence of the Fe-S cluster.

The parasitic protozoan Trypanosoma brucei has a single mitochondrial nucleoid, anchored to the basal body of the flagellum via the tripartite attachment complex (TAC). The detergent-insoluble TAC is essential for mitochondrial genome segregation during cytokinesis. The TAC assembles de novo in a directed way from the probasal body towards the kDNA.

This study investigates how hydrophobic and hydrophilic modifications at the C-terminus of the base peptide, KFEFEFKFK (KbpK), affect the hydrogel macroscopic properties. By the incorporation of phenylalanine (F, hydrophobic) and lysine (K, hydrophilic) residues, four variants, KbpK-K, KbpK-F, KbpK-KF, and KbpK-FK, were designed and evaluated. pH-concentration phase diagrams and Fourier transform infrared confirmed clear links showing how peptide hydrophobicity and charge influence β-sheet formation and macroscopic phase behavior.

BRCA2 is crucial for mediating homology-directed DNA repair (HDR) through its binding to single-stranded DNA (ssDNA) and the recombinases RAD51 and DMC1. Most BRCA2 orthologs have a canonical DNA-binding domain (DBD) with the exception of Drosophila melanogaster. It remains unclear whether such a noncanonical BRCA2 variant without DBD possesses a DNA-binding activity.

d-Amino acid oxidase from (DAAO) is valuable for pharmaceutical and chemical synthesis due to its high enantioselectivity, but its poor thermostability limits extensive application. This study proposed a synergistic strategy of "sequence consensus design coupled with structure modification" to enhance DAAO thermostability. Through homologous sequence analysis and greedy algorithm-based optimization, a triple mutant M3 (S18T/V7I/Y132F) was obtained, showing a 3.
