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 ...

This Is the End: Regulation of Rab7 Nucleotide Binding in Endolysosomal Trafficking and Autophagy
Frontiers in Cell and Developmental Biology, 2018 Rab7 – or in yeast, Ypt7p – governs membrane trafficking in the late endocytic and autophagic pathways. Rab7 also regulates mitochondrion-lysosome contacts, the sites of mitochondrial fission.

The Ras GTPase-activating protein Rasal3 supports survival of naive T cells. [PDF]
PLoS ONE, 2015 The Ras-mitogen-activated protein kinase (MAPK) pathway is crucial for T cell receptor (TCR) signaling in the development and function of T cells. The significance of various modulators of the Ras-MAPK pathway in T cells, however, remains to be fully ...

Beyond the GTP‐cap: Elucidating the molecular mechanisms of microtubule catastrophe
BioEssays, Volume 45, Issue 1, January 2023., 2023 Microtubule dynamics are essential for myriad cellular processes. The switching between microtubule growth and shrinkage is traditionally explained by the loss of a protective “cap” of GTP‐bound tubulin subunits from the growing microtubule end. New research shows that features beyond the nucleotide content at the growing end impact microtubule ...

Roles of Rap1 signaling in tumor cell migration and invasion
Cancer Biology & Medicine, 2017 Ras-associated protein-1 (Rap1), a small GTPase in the Ras-related protein family, is an important regulator of basic cellular functions (e.g., formation and control of cell adhesions and junctions), cellular migration, and polarization.

Cancer Communications, Volume 42, Issue 12, Page 1367-1386, December 2022., 2022 Abstract Background Neuroendocrine carcinomas of the gastrointestinal tract (GI‐NECs) remain a disease of grim prognosis with limited therapeutic options. Their molecular characteristics are still undefined. This study aimed to explore the underlying genetic basis and heterogeneity of GI‐NECs.

Spatiotemporal Regulation of Rho GTPases in Neuronal Migration
Cells, 2019 Neuronal migration is essential for the orchestration of brain development and involves several contiguous steps: interkinetic nuclear movement (INM), multipolar−bipolar transition, locomotion, and translocation.

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.

Advances in exosome biomarkers for cervical cancer
Cancer Medicine, Volume 11, Issue 24, Page 4966-4978, December 2022., 2022 Cancer‐derived exosomes may promote CC metastasis by boosting cellular epithelial‐mesenchymal transformation (EMT), controlling the proliferation, invasion, or migration of cancer cells, as well as influencing immune escape and aiding angiogenesis.
