Directed Evolution of Substrate-Optimized GroEL/S Chaperonins [PDF]

open access: yes, 2002
GroEL/S chaperonin ring complexes fold many unrelated proteins. To understand the basis and extent of the chaperonin substrate spectrum, we used rounds of selection and DNA shuffling to obtain GroEL/S variants that dramatically enhanced folding of a ...

Bardet–Biedl Syndrome Presenting With Acute Kidney Injury Revealing Previously Undiagnosed Advanced Chronic Kidney Disease in a Young Adult: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 10, October 2026.
ABSTRACT Bardet–Biedl syndrome (BBS) is an autosomal recessive disorder characterized by obesity, rod‐cone dystrophy, polydactyly, developmental delay, renal dysfunction, and genitourinary abnormalities. We report the case of a 27‐year‐old female with previously undiagnosed BBS who presented with acute kidney injury precipitated by acute ...

Bardet-Biedl Syndrome as a Chaperonopathy: Dissecting the Major Role of Chaperonin-Like BBS Proteins (BBS6-BBS10-BBS12)

open access: yesFrontiers in Molecular Biosciences, 2017
Bardet-Biedl syndrome (BBS) is a rare genetic disorder that belongs to the group of ciliopathies, defined as diseases caused by defects in cilia structure and/or function. The six diagnostic features considered for this syndrome include retinal dystrophy,

Posttranslational Modifications of p62/SQSTM1 in Health and Disease

open access: yesMedComm, Volume 7, Issue 10, October 2026.
Schematic illustration of p62 as a posttranslational modifications (PTMs)‐programmed integrator in homeostasis, pathogenesis, and therapeutic targeting. (Left) Homeostasis: In physiological states, p62, through various PTMs such as phosphorylation, ubiquitination, and acetylation, coordinates essential cellular functions.

Global Proteomic Analysis of Sperm and Seminal Plasma From Tropically‐Adapted Rams With Contrasting Parameters of Frozen‐Thawed Semen

open access: yesMolecular Reproduction and Development, Volume 93, Issue 10, October 2026.
ABSTRACT The aim of this study was to characterize the proteome of sperm and seminal plasma (SP) from rams with high semen freezability (HF) and low semen freezability (LF). Eleven ejaculates were collected from 12 rams, at 3‐day intervals, and cryopreserved (132 semen samples).

Chaperonins from an Antarctic archaeon are predominantly monomeric: crystal structure of an open state monomer

open access: yes, 2011
Archaea are abundant in permanently cold environments. The Antarctic methanogen, Methanococcoides burtonii, has proven an excellent model for studying molecular mechanisms of cold adaptation.

Controlling Geminiviruses before Transmission: Prospects

open access: yesPlants, 2020
Whitefly (Bemisia tabaci)-transmitted Geminiviruses cause serious diseases of crop plants in tropical and sub-tropical regions. Plants, animals, and their microbial symbionts have evolved complex ways to interact with each other that impact their life ...

Application of Omics Technologies for Cowpea Improvement

open access: yesPlant-Environment Interactions, Volume 7, Issue 5, October 2026.
ABSTRACT Cowpea (Vigna unguiculata) is a vital crop for food security, nutrition, and climate resilience in sub‐Saharan African and other semi‐arid regions. However, its improvement is constrained by the complexity of polygenic traits such as drought tolerance, pest resistance, and seed quality.

Chaperonin of Group I: Oligomeric Spectrum and Biochemical and Biological Implications

open access: yesFrontiers in Molecular Biosciences, 2018
Chaperonins play various physiological roles and can also be pathogenic. Elucidation of their structure, e.g., oligomeric status and post-translational modifications (PTM), is necessary to understand their functions and mechanisms of action in health and
