GTP-Binding Proteins and Regulated Exocytosis [PDF]
Critical Reviews in Oral Biology & Medicine, 1999 Regulated exocytosis, which occurs in response to stimuli, is a two-step process involving the docking of secretory granules (SGs) at specific sites on the plasma membrane (PM), with subsequent fusion and release of granule contents. This process plays a crucial role in a number of tissues, including exocrine glands, chromaffin cells, platelets, and ...

In silico evidence that protein unfolding is as a precursor of the protein aggregation [PDF]
ChemPhysChem 2020, 21, 377, 2019 We present a computational study on the folding and aggregation of proteins in aqueous environment, as function of its concentration. We show how the increase of the concentration of individual protein species can induce a partial unfolding of the native conformation without the occurrence of aggregates. A further increment of the protein concentration

Gαs slow conformational transition upon GTP binding and a novel Gαs regulator
iScience, 2023 Summary: G proteins are major signaling partners for G protein-coupled receptors (GPCRs). Although stepwise structural changes during GPCR–G protein complex formation and guanosine diphosphate (GDP) release have been reported, no information is available

A novel methodology on distributed representations of proteins using their interacting ligands [PDF]
Bioinformatics 2018, 2018 The effective representation of proteins is a crucial task that directly affects the performance of many bioinformatics problems. Related proteins usually bind to similar ligands. Chemical characteristics of ligands are known to capture the functional and mechanistic properties of proteins suggesting that a ligand based approach can be utilized in ...

IQGAP Family Members in Yeast, Dictyostelium, and Mammalian Cells
International Journal of Cell Biology, 2012 IQGAPs are a family of scaffolding proteins with multiple domains, named for the IQ motifs and GTPase activating protein (GAP) related domains. Despite their GAP homology, IQGAP proteins act as effectors for GTP-bound GTPases of the Ras superfamily and ...

Molecules and mechanisms that regulate multipolar migration in the intermediate zone
Frontiers in Cellular Neuroscience, 2014 Most neurons migrate with an elongated, bipolar morphology, extending a long leading process that explores the environment. However, when immature projection neurons enter the intermediate zone of the neocortex they become multipolar.

The GTP- and Phospholipid-Binding Protein TTD14 Regulates Trafficking of the TRPL Ion Channel in Drosophila Photoreceptor Cells. [PDF]
PLoS Genetics, 2015 Recycling of signaling proteins is a common phenomenon in diverse signaling pathways. In photoreceptors of Drosophila, light absorption by rhodopsin triggers a phospholipase Cβ-mediated opening of the ion channels transient receptor potential (TRP) and ...

Divergent Mechanisms Activating RAS and Small GTPases Through Post-translational Modification
Frontiers in Molecular Biosciences, 2021 RAS is a founding member of the RAS superfamily of GTPases. These small 21 kDa proteins function as molecular switches to initialize signaling cascades involved in various cellular processes, including gene expression, cell growth, and differentiation ...

Septin6 and Septin7 GTP binding proteins regulate AP-3- and ESCRT-dependent multivesicular body biogenesis. [PDF]
PLoS ONE, 2014 Septins (SEPTs) form a family of GTP-binding proteins implicated in cytoskeleton and membrane organization, cell division and host/pathogen interactions. The precise function of many family members remains elusive.

Virtual Identification of Essential Proteins Within the Protein Interaction Network of Yeast [PDF]
, 2005 Topological analysis of large scale protein-protein interaction networks (PINs) is important for understanding the organisational and functional principles of individual proteins. The number of interactions that a protein has in a PIN has been observed to be correlated with its indispensability.
