N-glycosylation in the SERPIN domain of C1-Esterase Inhibitor in hereditary angioedema.

Hereditary angioedema is an autosomal dominant disorder caused by defects in C1-esterase inhibitor (C1-INH), resulting in poorly controlled activation of the kallikrein-kinin system and bradykinin overproduction. C1-INH is a heavily glycosylated protein in the serine protease inhibitor (SERPIN) family, yet the role of these glycosylation sites remains unclear. To elucidate the functional impact of N-glycosylation in the SERPIN domain of C1-INH, we engineered four sets consisting of 26 variants at or near the N-linked sequon (NXS/T).

The strand exchange domain of tumor suppressor PALB2 is intrinsically disordered and promotes oligomerization-dependent DNA compaction.

The partner and localizer of BRCA2 (PALB2) is a scaffold protein linking BRCA1 with BRCA2 and RAD51 during homologous recombination (HR). PALB2 interaction with DNA strongly enhances HR in cells, while the PALB2 DNA-binding domain (PALB2-DBD) supports DNA strand exchange . We determined that PALB2-DBD is intrinsically disordered beyond a single N-terminal α-helix.

Mechanistic basis of activation and inhibition of protein disulfide isomerase by allosteric antithrombotic compounds.

Background: Protein disulfide isomerase (PDI) is a promising target for combating thrombosis. Extensive research over the past decade has identified numerous PDI-targeting compounds. However, limited information exists regarding how these compounds control PDI activity, which complicates further development.

[Psychiatric symptoms of Huntington's disease].

Huntington's disease (HD) is an autosomal dominant inherited disease, which leads to motor, cognitive and psychiatric symptoms. The diagnosis can be confirmed by genetic testing for extended CAG repeats in the Huntingtin gene. Mental and behavioral symptoms are common in HD and can appear several years before the onset of motor symptoms.
