A Model for Direction Sensing in Dictyostelium Discoideum: Ras Activity and Symmetry Breaking Driven by a Gbetagamma- Mediated, Galpha2-Ric8 -- Dependent Signal Transduction Network

open access: yes, 2015
Many eukaryotic cells, including Dictyostelium discoideum (Dicty), neutrophils and other cells of the immune system, can detect and reliably orient themselves in chemoattractant gradients.

The Cool-2/α-Pix Protein Mediates a Cdc42-Rac Signaling Cascade [PDF]

open access: yes, 2005
Background:Cloned-out of library-2 (Cool-2)/PAK-interactive exchange factor (α-Pix) was identified through its ability to bind the Cdc42/Rac target p21-activated kinase (PAK) and has been implicated in certain forms of X-linked mental retardation as well

Novel insights into the assembly of the yeast translation initiation multifactor complex: The critical role of eIF5

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract The eukaryotic translation initiation is a biological process in which at least a dozen eukaryotic initiation factors (eIFs) are involved. Specifically, eIF3, eIF1, eIF5, and eIF2 as a ternary complex (eIF2‐TC) bound to GTP and methionyl initiator tRNA (Met‐tRNAiMet).

Structural and functional insights into TBC1D17 highlight the importance of the previously uncharacterized Rab‐binding domain

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract TBC (Tre2/Bub2/Cdc16) domain‐containing proteins constitute the widespread family of GTPase‐activating proteins (GAPs). They interact with the Rab superfamily of small GTPases, stimulate GTP hydrolysis, and regulate vesicle trafficking. TBC1D17, involved in Shiga toxin trafficking, autophagy and glucose metabolism regulation, constitutes an ...

Ethanol Induced Disordering of Pancreatic Acinar Cell Endoplasmic Reticulum: An ER Stress/Defective Unfolded Protein Response Model. [PDF]

open access: yes, 2018
Background & aimsHeavy alcohol drinking is associated with pancreatitis, whereas moderate intake lowers the risk. Mice fed ethanol long term show no pancreas damage unless adaptive/protective responses mediating proteostasis are disrupted. Pancreatic

Gap Analysis of Metabolic Conversions of Off‐Flavors and Antinutrients in Plant‐Based Substrates

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT To drastically reduce the carbon footprint of the food production chain, a major shift towards alternatives to conventional meat and dairy products is required. The use of plant‐based proteins is a promising route, but it also comes with challenges: Plant‐based proteins often contain antinutritional factors and off‐flavors, which can ...

Assignments of backbone 1H, 13C and 15N resonances in H-Ras (1–166) complexed with GppNHp at physiological pH [PDF]

open access: yes, 2012
The small GTPase Ras is an important signaling molecule acting as a molecular switch in eukaryotic cells. Recent findings of global conformational exchange and a putative allosteric binding site in the G domain of Ras opened an avenue to understanding ...

Luteinizing hormone receptor knockout mouse: What has it taught us?

open access: yesAndrology, Volume 14, Issue 4, Page 1017-1028, May 2026.
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Autoinhibition of the formin Cappuccino in the absence of canonical autoinhibitory domains. [PDF]

open access: yes, 2012
Formins are a conserved family of proteins known to enhance actin polymerization. Most formins are regulated by an intramolecular interaction. The Drosophila formin, Cappuccino (Capu), was believed to be an exception.
