OsCPN10a, cooperating with OsCPN20 and OsHSP60‐3B negatively regulate ABA signaling and enhance seed storability in rice

Journal of Integrative Plant Biology, EarlyView.
Abscisic acid signaling homeostasis is essential for seed storability. The molecular chaperone OsCPN10a enhances rice seed storability by forming a trimeric chaperone complex with OsCPN20‐OsHSP60‐3B that attenuates abscisic acid signaling via direct interaction with OsPYL10‐OsABIL1, thereby maintaining starch integrity and offering a promising target ...

The Relationship between Age at First Birth and Mother's Lifetime Earnings: Evidence from Danish Data. [PDF]

PLoS ONE, 2016
Having children creates career interruptions and reductions in labor income for women. This study documents the relation between the age at first birth (AFB) and women's labor income. We study these dynamics in the short run (i.e.

Outer Membrane Vesicles Mediate the Secretion and Nuclear Trafficking of a Bacterial Nucleomodulin

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
(A) We propose that Helicobacter pylori secretes a nucleomodulin, Tumour Necrosis Factor‐α‐inducing protein (Tipα), predominantly via extracellular vesicles (EVs), also known as outer membrane vesicles, rather than as free protein. (B) EVs carrying Tipα enter eukaryotic cells by endocytosis and independently of surface‐expressed nucleolin, then traffic

Use of a Chimeric Hsp70 to Enhance the Quality of Recombinant Plasmodium falciparum S-Adenosylmethionine Decarboxylase Protein Produced in Escherichia coli. [PDF]

PLoS ONE, 2016
S-adenosylmethionine decarboxylase (PfAdoMetDC) from Plasmodium falciparum is a prospective antimalarial drug target. The production of recombinant PfAdoMetDC for biochemical validation as a drug target is important.

Phosphate Limitation Modulates Vibrio Cholerae Outer Membrane Vesicle Formation, Composition and Toxicity

Journal of Extracellular Biology, Volume 5, Issue 5, May 2026.
ABSTRACT Vibrio cholerae inhabits phosphorus‐poor aquatic environments and host intestine, where it expresses genes regulated by the PhoB/PhoR two‐component system in response to inorganic phosphate (Pi) limitation. Like other Gram‐negative bacteria, V.

Family‐level specialization in protein domain insertion architectures

Protein 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

Multi-scale simulations provide supporting evidence for the hypothesis of intramolecular protein translocation in GroEL/GroES complexes. [PDF]

PLoS Computational Biology, 2008
The biological function of chaperone complexes is to assist the folding of non-native proteins. The widely studied GroEL chaperonin is a double-barreled complex that can trap non-native proteins in one of its two barrels.

Determination of the Number of Active GroES Subunits in the Fused Heptamer GroES Required for Interactions with GroEL [PDF]

Journal of Biological Chemistry, 2008
A double-heptamer ring chaperonin GroEL binds denatured substrate protein, ATP, and GroES to the same heptamer ring and encapsulates substrate into the central cavity underneath GroES where productive folding occurs. GroES is a disk-shaped heptamer, and each subunit has a GroEL-binding loop.

Protein Language Model‐Guided Engineering of a 2,3‐Butanediol Dehydrogenase for the Enantioselective Synthesis of Cyclic α‐Hydroxy Ketones

Advanced Science, Volume 13, Issue 18, 27 March 2026.
A (2R,3R)‐butanediol dehydrogenase from Bacillus subtilis (BsBDH) is engineered for the enantioselective synthesis of 2‐hydroxycyclohexanone. A PASS computational design strategy is proposed to enhance the thermostability of BsBDH. Moreover, ESM‐1v combined with ISM is utilized for enhancing and inverting its stereoselectivity.

P. falciparum cpn20 is a bona fide co-chaperonin that can replace GroES in E. coli. [PDF]

PLoS ONE, 2013
Human malaria is among the most ubiquitous and destructive tropical, parasitic diseases in the world today. The causative agent, Plasmodium falciparum, contains an unusual, essential organelle known as the apicoplast.
