YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

open access: yesFEBS Open Bio, EarlyView.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

Oscillation criteria for forced second-order mixed type quasilinear delay differential equations

open access: yesElectronic Journal of Differential Equations, 2010
This article presents new oscillation criteria for the second-order delay differential equation $$ (p(t) (x'(t))^{alpha})' + q(t) x^{alpha}(t - au) + sum_{i = 1}^{n} q_{i}(t) x^{alpha_{i}}(t - au) = e(t) $$ where $au geq 0$, $p(t) in C^1[0, infty)$,

MiR‐513a promotes human erythroid differentiation by modulating c‐Jun

open access: yesFEBS Open Bio, EarlyView.
During early human erythropoiesis, miR‐513a promoted erythroid differentiation in primary human CD34+ hematopoietic stem‐progenitor cells and human TF‐1 erythroleukemic cells by indirectly decreasing c‐Jun and phospho‐c‐Jun expression, which are associated with increased GATA1 expression.

Decreased cold‐sensing function of the transient receptor potential channel TRPM8 from tailed amphibians

open access: yesFEBS Open Bio, EarlyView.
Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system

open access: yesFEBS Open Bio, EarlyView.
An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...

Annulus oscillation criteria for second order nonlinear elliptic differential equations with damping

open access: yesElectronic Journal of Differential Equations, 2009
We establish oscillation criteria for the second-order elliptic differential equation $$ ablacdot(A(x) abla y)+B^T(x) abla y+q(x)f(y)=e(x), quad xinOmega, $$ where $Omega $ is an exterior domain in $mathbb{R}^N$.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

open access: yesFEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

open access: yesFEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Interval criteria for oscillation of second-order impulsive differential equation with mixed nonlinearities

open access: yesElectronic Journal of Differential Equations, 2011
We establish sufficient conditions for the oscillation of all solutions to the second-order impulsive differential equation $$displaylines{ ig(r(t)x'(t)ig)'+p(t)x'(t)+q(t)x(t)+sum_{i=1}^n q_i(t)|x(t)|^{alpha_i}hbox{sgn} x(t)=e(t),quad teq au_k,cr x({

The skills required for transition to university and study in biological sciences: A student perspective

open access: yesFEBS Open Bio, EarlyView.
Bioscience students were asked for their opinions on the value and teaching of skills. 204 responded that teamwork, time management and study skills are necessary to reach University, that scientific writing, research, laboratory and presentation skills are taught effectively during their studies, while other skills are gained inherently through study ...
