RhoA and Rac1 as Mechanotransduction Mediators in Colorectal Cancer

open access: yesAdvanced Biology, EarlyView.
Analysing RhoA and Rac1 protein levels in Colorectal cancer (CRC) samples under mechanical strain highlights their potential as diagnostic markers. Monitoring their activity could offer valuable insights into how cancer spreads, paving the way for new approaches to better understand and diagnose colorectal cancer.

Dissection of GTPase activating proteins reveals functional asymmetry in the COPI coat of budding yeast. [PDF]

open access: yes, 2019
The Arf GTPase controls formation of the COPI vesicle coat. Recent structural models of COPI revealed the positioning of two Arf1 molecules in contrasting molecular environments.

The Regulation of Trace Metal Elements in Cancer Ferroptosis

open access: yesAdvanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

A process model of Rho GTP-binding proteins

open access: yesTheoretical Computer Science, 2009
AbstractRho GTP-binding proteins play a key role as molecular switches in many cellular activities. In response to extracellular stimuli and with the help of regulators (GEF, GAP, Effector, GDI), these proteins serve as switches that interact with their environment in a complex manner.

IncRNA‐ZFAS1, an Emerging Gate‐Keeper in DNA Damage‐Dependent Transcriptional Regulation

open access: yesAdvanced Science, EarlyView.
LncZFAS1 plays a crucial role during DNA damage response in mammalian cells. Loss of lncZFAS1 results in deficient DNA lesion removal and reduced cell viability. Mechanistically, lncZFAS1 modulates RNAPII phosphorylation and transcription and thereby promotes both GG‐NER and TC‐NER upon UV damage.

Activation of phospholipase C beta4 by heterotrimeric GTP-binding proteins [PDF]

open access: yes, 1994
Transient transfection assays were used to determine how the activity of phospholipase C beta 4, which is preferentially expressed in retina, was regulated.

A putative ATPase mediates RNA transcription and capping in a dsRNA virus. [PDF]

open access: yes, 2015
mRNA transcription in dsRNA viruses is a highly regulated process but the mechanism of this regulation is not known. Here, by nucleoside triphosphatase (NTPase) assay and comparisons of six high-resolution (2.9-3.1 Å) cryo-electron microscopy structures ...

A Supramolecular Material for Controlling Kiwifruit Bacterial Canker

open access: yesAdvanced Science, EarlyView.
The matrine‐5‐methylsalicylic acid salt (MOS) is reported for its excellent antibacterial activity against Pseudomonas syringae pv. actinidiae (Psa), with advanced cell membrane penetration ability and strong affinities for potential targets. Furthermore, a nanosupramolecular delivery system MOS@hydroxypropyl‐beta‐cyclodextrin (HPCD) with improved ...

Cofactor Fingerprinting with STD NMR to Characterize Proteins of Unknown Function: Identification of a Rare cCMP Cofactor Preference [PDF]

open access: yes, 2004
Proteomics efforts have created a need for better strategies to functionally categorize newly discovered proteins. To this end, we have employed saturation transfer difference NMR with pools of closely related cofactors, to determine cofactor preferences.

The ciliary machinery is repurposed for T cell immune synapse trafficking of LCK [PDF]

open access: yes, 2018
Upon engagement of the T cell receptor with an antigen-presenting cell, LCK initiates TCR signaling by phosphorylating its activation motifs. However, the mechanism of LCK activation specifically at the immune synapse is a major question.
