A Ras-GTPase-Activating Protein SH3-Domain-Binding Protein [PDF]

Molecular and Cellular Biology, 1996
We report the purification of a Ras-GTPase-activating protein (GAP)-binding protein, G3BP, a ubiquitously expressed cytosolic 68-kDa protein that coimmunoprecipitates with GAP. G3BP physically associates with the SH3 domain of GAP, which previously had been shown to be essential for Ras signaling.

Functional specialization of the yeast Rho1 GTP exchange factors [PDF]

, 2012
Rho GTPases are regulated in complex spatiotemporal patterns that may be dependent, in part at least, on the multiplicity of their GTP exchange factors (GEFs).

Potent Liver‐Tropic mRNA Lipid Nanoparticles: ApoE‐Mediated Delivery Through a Low‐Density Lipoprotein Receptor Independent Uptake Mechanism

Advanced Materials, EarlyView.
Helper and ionizable lipids play a crucial role in determining ApoE binding and subsequent liver tropism and LDLR‐mediated uptake. Ionizable lipids primarily govern the LDLR‐independent uptake pathway. This complementary interplay between lipid components ultimately governs LNP delivery performance and therapeutic efficacy in the liver.

Retromer subunit, VPS29, regulates synaptic transmission and is required for endolysosomal function in the aging brain

eLife, 2020
Retromer, including Vps35, Vps26, and Vps29, is a protein complex responsible for recycling proteins within the endolysosomal pathway. Although implicated in both Parkinson’s and Alzheimer’s disease, our understanding of retromer function in the adult ...

No evidence for oncogenic mutations in guanine nucleotide-binding proteins of human adrenocortical neoplasms [PDF]

, 1933
G-Proteins are membrane-bound heterotrimeric polypeptides that couple receptor signals to second messenger systems such as cAMP. Recently, point mutations at 2 codons of the highly preserved alpha-chain of Gs, the adenyl cyclase-stimulating G-protein ...

7-Keto-Cholesterol and Cholestan-3beta, 5alpha, 6beta-Triol Induce Eryptosis through Distinct Pathways Leading to NADPH Oxidase and Nitric Oxide Synthase Activation [PDF]

, 2019
BACKGROUND/AIMS: We showed that patho-physiological concentrations of either 7-keto-cholesterol (7-KC), or cholestane-3beta, 5alpha, 6beta-triol (TRIOL) caused the eryptotic death of human red blood cells (RBC), strictly dependent on the early production

Mettl3‐Mediated m6A Modification Represents a Novel Therapeutic Target for FSGS

Advanced Science, EarlyView.
This study explores the roles of Mettl3‐induced N6‐methyladenosine (m6A) modifications in Focal segmental glomerulosclerosis (FSGS). The findings reveal that inhibition of Mettl3 results in podocyte injury by modulating the TJP1CDC42 pathway. Moreover, Administration of N6‐methyladenosine attenuates the FSGS phenotype in WT mice induced by Adriamycin ...

Identification of PKN2 and MOB4 as Coordinators of Collective Cell Migration

Advanced Science, EarlyView.
Through a genetic screen, PKN2 and MOB4 are identified as two proteins regulating the healing of an epithelial model wound. PKN2 promotes collective cell migration by maintaining the cohesion of cell monolayers from their lateral junctions, whereas MOB4 restrains collective cell migration and provides a lamellipodial cue for front‐rear polarity in ...
