Saccharomyces cerevisiae and Schizosaccharomyces pombe contain a homologue to the 54-kD subunit of the signal recognition particle that in S. cerevisiae is essential for growth. [PDF]

open access: yes, 1989
We have isolated and sequenced genes from Saccharomyces cerevisiae (SRP54SC) and Schizosaccharomyces pombe (SRP54sp) encoding proteins homologous to both the 54-kD protein subunit (SRP54mam) of the mammalian signal recognition particle (SRP) and the ...

Dual positive and negative regulation of GPCR signaling by GTP hydrolysis [PDF]

open access: yes, 2009
G protein-coupled receptors (GPCRs) regulate a variety of intracellular pathways through their ability to promote the binding of GTP to heterotrimeric G proteins. Regulator of G protein signaling (RGS) proteins increase the intrinsic GTPase activity of G-

Long Term High‐Salt Diet Induces Cognitive Impairments via Down‐Regulating SHANK1

open access: yesAdvanced Science, EarlyView.
The study identifies a novel mechanistic link between long‐term HS diet and cognitive impairment, wherein PKA/CREB axis inactivation leads to SHANK1 reduction, synaptic damage, and cognitive deficits. Abstract High‐salt (HS) diet is an established risk factor for cognitive impairment, but the underlying mechanisms remain unclear.

TBC1D22B Regulates ER‐to‐Golgi Trafficking via RAB1B Inactivation and Promotes Oncogenic Programs in Breast Cancer

open access: yesAdvanced Science, EarlyView.
TBC1D22B, a Golgi‐localized RabGAP linked to poor prognosis in breast cancer, inhibits ER‐to‐Golgi transport via RAB1B inactivation. This disrupts secretion, drives oncogenic transcriptional reprogramming, and promotes tumor growth. These findings indicate that TBC1D22B connects membrane trafficking to transcriptional control and cancer progression ...

The gateway to chloroplast: re-defining the function of chloroplast receptor proteins [PDF]

open access: yes, 2012
Chloroplast biogenesis often requires a tight orchestration between gene expression (both plastidial and nuclear) and translocation of similar to 3000 nuclear-encoded proteins into the organelle.

A Comprehensive Lateral Flow Strip Assay for On‐Site mRNA Vaccine Quality Control in Decentralized Manufacturing

open access: yesAdvanced Science, EarlyView.
A rapid, portable lateral flow strip assay for on‐site mRNA quality control is developed, enabling sequence‐independent analysis of 5' capping, integrity, and LNPs encapsulation efficiency. This cost‐effective method offers real‐time stability monitoring, reduced sample requirements, and comparable accuracy to standard techniques, enhancing ...

Molecular Aspects of Secretory Granule Exocytosis by Neurons and Endocrine Cells [PDF]

open access: yes, 1994
Neuronal communication and endocrine signaling are fundamental for integrating the function of tissues and cells in the body. Hormones released by endocrine cells are transported to the target cells through the circulation.

Protein Secretion and GTP-binding Proteins.

open access: yesSeibutsu Butsuri, 1991
GTP-binding proteins are involved in a wide variety of cellular functions. One of the most recent findings is the implication of many GTP-binding proteins in the pathway of protein secretion. In the eukaryotic secretory pathway, proteins have to be sorted from each other at many steps, including the signal recognition and translocation across the ...

Nomenclature for the human Arf family of GTP-binding proteins: ARF, ARL, and SAR proteins

open access: yesJournal of Cell Biology, 2006
The Ras superfamily is comprised of at least four large families of regulatory guanosine triphosphate–binding proteins, including the Arfs. The Arf family includes three different groups of proteins: the Arfs, Arf-like (Arls), and SARs.

Epigenetic Regulation of DAPK1 and Netrin‐1 Drives Diabetic Encephalopathy

open access: yesAdvanced Science, EarlyView.
This study identifies a microRNA (miR)‐216a‐5p/death‐associated protein kinase 1 (DAPK1)/hepatocyte nuclear factor 1 homeobox A (HNF1A)/Netrin‐1 signaling axis in diabetic encephalopathy (DE). In leptin receptor‐deficient (db/db) and streptozotocin (STZ)‐induced diabetic mice, reduced miR‐216a‐5p increases DAPK1 expression, disrupting HNF1A binding to ...
