Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

FEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Elucidating the genetic mechanisms governing cytosine base editing outcomes through CRISPRi screens

Nature Communications
Cytosine base editors enable programmable and efficient genome editing using an intermediate featuring a U•G mismatch across from a DNA nick. This intermediate facilitates two major outcomes, C•G to T•A and C•G to G•C point mutations, and it is not ...

Competitive Oligonucleotide Single-Base Extension Combined with Mass Spectrometric Detection for Mutation Screening

BioTechniques, 1997
A rapid, robust and widely applicable mutation detection scheme not requiring radioactivity or gel-based detection is introduced. It is a single-tube, competitive oligonucleotide single-base extension (COSBE) reaction using a pair of primers with the 3 ...

Why human connection is the true metric of research success

FEBS Open Bio, EarlyView.
Human‐centred mentorship can be shaped by mentor attributes, actions, intrinsic drive and career ambition. Drawing on reflections across Singapore and France, as well as workshop insights from FEBS‐IUBMB ENABLE 2024, this article shows that human‐centred mentorship creates the conditions for sustainable growth, well‐being and retention in research ...

Mismatch repair balances leading and lagging strand DNA replication fidelity.

PLoS Genetics, 2012
The two DNA strands of the nuclear genome are replicated asymmetrically using three DNA polymerases, α, δ, and ε. Current evidence suggests that DNA polymerase ε (Pol ε) is the primary leading strand replicase, whereas Pols α and δ primarily perform ...

Sequence variants affecting the genome-wide rate of germline microsatellite mutations

Nature Communications, 2023
Microsatellites are polymorphic tracts of short tandem repeats with one to six base-pair (bp) motifs and are some of the most polymorphic variants in the genome.

Clustering Algorithm Reveals Dopamine‐Motor Mismatch in Cognitively Preserved Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore the relationship between dopaminergic denervation and motor impairment in two de novo Parkinson's disease (PD) cohorts. Methods n = 249 PD patients from Parkinson's Progression Markers Initiative (PPMI) and n = 84 from an external clinical cohort.

Directional R-Loop Formation by the CRISPR-Cas Surveillance Complex Cascade Provides Efficient Off-Target Site Rejection

Cell Reports, 2015
CRISPR-Cas systems provide bacteria and archaea with adaptive immunity against foreign nucleic acids. In type I CRISPR-Cas systems, invading DNA is detected by a large ribonucleoprotein surveillance complex called Cascade.

Studies of the structure and stability of base pair mismatches, base pairs involving modified bases, and DNA-drug complexes

Journal of Chemical Crystallography, 1994
Of the DNA bases, the hydrogen bonding characteristics of guanine (G) are complementary only to those of cytidine (C) and, similarly, the hydrogen bonding characteristics of adenine (A) are complementary only to those of thymine (T) (Fig. 1). This is the fundamental basis of Watson-Crick base pairing in DNA and ensures the extremely high fidelity of ...

Structure–Function Decoupling of the Sensorimotor and Default Mode Networks in Black Americans With MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Multiple sclerosis (MS) exhibits racially disparate rates of disease progression. Black people with MS (B‐PwMS) experience a more severe disease course than non‐Hispanic White people with MS (NHW‐PwMS). Here we investigated structural and functional connectivity as well as structure–function decoupling in the ...
