Age-related guanine nucleotide exchange factor, mouse Zizimin2, induces filopodia in bone marrow-derived dendritic cells

open access: yesImmunity & Ageing, 2012
Background We recently isolated and identified Zizimin2 as a functional factor that is highly expressed in murine splenic germinal center B cells after immunization with T-cell-dependent antigen.

Thermodynamic and kinetic insights into stop codon recognition by release factor 1. [PDF]

open access: yes, 2014
Stop codon recognition is a crucial event during translation termination and is performed by class I release factors (RF1 and RF2 in bacterial cells). Recent crystal structures showed that stop codon recognition is achieved mainly through a network of ...

A Histidine pH sensor regulates activation of the Ras-specific guanine nucleotide exchange factor RasGRP1

open access: yeseLife, 2017
RasGRPs are guanine nucleotide exchange factors that are specific for Ras or Rap, and are important regulators of cellular signaling. Aberrant expression or mutation of RasGRPs results in disease. An analysis of RasGRP1 SNP variants led to the conclusion

Structural basis for the sequence-specific RNA-recognition mechanism of human CUG-BP1 RRM3 [PDF]

open access: yes, 2009
The CUG-binding protein 1 (CUG-BP1) is a member of the CUG-BP1 and ETR-like factors (CELF) family or the Bruno-like family and is involved in the control of splicing, translation and mRNA degradation.

Reduced Dietary Protein Induces Changes in the Dental Proteome

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Low dietary protein (10%) from normal (20%) does change protein expression in tooth proteome and alter developmental pathways. Among the significant protein expressions changes are actin‐based myosins, tooth, and bone development proteins. Perplexingly tooth size is not altered, suggesting more nuanced phenotypic response to low dietary protein in ...

Light‐Based Molecular Tools to Precisely Monitor and Operate β‐Adrenoceptors

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT β‐Adrenoceptors are important G protein–coupled receptors involved in cardiovascular, metabolic, and neurological regulation. To study their function with high precision, light‐based molecular tools have been developed offering precise spatiotemporal control.

SGEF is a potential prognostic and therapeutic target for lung adenocarcinoma

open access: yesWorld Journal of Surgical Oncology, 2018
Background SH3-containing guanine nucleotide exchange factor (SGEF), a RhoG-specific guanine nucleotide exchange factor (GEF), was consider as a key signal that determines cancer cell invasion.

Gi- and Gs-coupled GPCRs show different modes of G-protein binding. [PDF]

open access: yes, 2018
More than two decades ago, the activation mechanism for the membrane-bound photoreceptor and prototypical G protein-coupled receptor (GPCR) rhodopsin was uncovered.

Recent Progress in Treating Airway Mucus Hypersecretion by Targeting the Epidermal Growth Factor Receptor Signaling Pathway

open access: yesPediatric Discovery, EarlyView.
ABSTRACT Asthma, chronic pulmonary obstructive disease (COPD), cystic fibrosis, and acute respiratory infections are severe respiratory conditions that significantly contribute to global morbidity and mortality. Airway mucus hypersecretion is an important common pathophysiological and clinical manifestation of these diseases and is closely associated ...
