Co-activation of RanGTPase and inhibition of GTP dissociation by Ran-GTP binding protein RanBP1. [PDF]

open access: yesThe EMBO Journal, 1995
RCC1 (the regulator of chromosome condensation) stimulates guanine nucleotide dissociation on the Ras-related nuclear protein Ran. Both polypeptides are components of a regulatory pathway that has been implicated in regulating DNA replication, onset of and exit from mitosis, mRNA processing and transport, and import of proteins into the nucleus.

GEF-independent Ran activation shifts a fraction of the protein to the cytoplasm and promotes cell proliferation

open access: yesMolecular Biomedicine, 2020
Ran (Ras-related nuclear protein) plays several important roles in nucleo-cytoplasmic transport, mitotic spindle formation, nuclear envelope/nuclear pore complex assembly, and other functions in the cytoplasm, as well as in cellular transformation when ...

Secretome profiling of Artemisia absinthium extract-loaded polymeric nanoparticle-treated MCF-7 and MDA-MB-231 revealed perturbation in microtubule assembly and cell migration

open access: yesFrontiers in Oncology, 2023
IntroductionArtemisia absinthium (wormwood) exhibits anticancer properties by inhibiting proliferation and causing cell death in breast cancer. Targeted drug delivery of A. absinthium nanoformulation using N-isopropyl acrylamide, N-vinyl pyrrolidone, and

Structural Insights into How Yrb2p Accelerates the Assembly of the Xpo1p Nuclear Export Complex

open access: yesCell Reports, 2014
Proteins and ribonucleoproteins containing a nuclear export signal (NES) assemble with the exportin Xpo1p (yeast CRM1) and Gsp1p-GTP (yeast Ran-GTP) in the nucleus and exit through the nuclear pore complex.

Comparative Proteomic Analysis of Anti-Cancer Mechanism by Periplocin Treatment in Lung Cancer Cells

open access: yesCellular Physiology and Biochemistry, 2014
Background: Periplocin is used for treatment of rheumatoid arthritis, reinforcement of bones and tendons, palpitations or shortness of breath and lower extremity edema in traditional medicine. Our previous findings suggested that periplocin could inhibit

Selective Impairment of a Subset of Ran-GTP-binding Domains of Ran-binding Protein 2 (Ranbp2) Suffices to Recapitulate the Degeneration of the Retinal Pigment Epithelium (RPE) Triggered by Ranbp2 Ablation [PDF]

open access: yesJournal of Biological Chemistry, 2014
Retinal pigment epithelium (RPE) degeneration underpins diseases triggered by disparate genetic lesions, noxious insults, or both. The pleiotropic Ranbp2 controls the expression of intrinsic and extrinsic pathological stressors impinging on cellular viability. However, the physiological targets and mechanisms controlled by Ranbp2 in tissue homeostasis,

The RanGTP pathway: from nucleo-cytoplasmic transport to spindle assembly and beyond

open access: yesFrontiers in Cell and Developmental Biology, 2016
The small GTPase Ran regulates the interaction of transport receptors with a number of cellular cargo proteins. The high affinity binding of the GTP-bound form of Ran to import receptors promotes cargo release, whereas its binding to export receptors ...

Topological and functional properties of the small GTPases protein interaction network. [PDF]

open access: yesPLoS ONE, 2012
Small GTP binding proteins of the Ras superfamily (Ras, Rho, Rab, Arf, and Ran) regulate key cellular processes such as signal transduction, cell proliferation, cell motility, and vesicle transport.

The importin beta superfamily member RanBP17 exhibits a role in cell proliferation and is associated with improved survival of patients with HPV+ HNSCC

open access: yesBMC Cancer, 2022
Background More than twenty years after its discovery, the role of the importin beta superfamily member Ran GTP-binding protein (RanBP) 17 is still ill defined.
