Induction of Ran GTP drives ciliogenesis [PDF]
, 2011 The small GTPase Ran and the importin proteins regulate nucleocytoplasmic transport. New evidence suggests that Ran GTP and the importins are also involved in conveying proteins into cilia.

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

The F-actin filament capping protein CapG is a bona fide nucleolar protein [PDF]
, 2008 Actin works in concert with myosin I to regulate the transcription of ribosomal genes in the nucleolus. Recently, nucleolar actin has been shown to be active in its polymeric form raising the question how actin dynamics is regulated in the nucleolus ...

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

Structural insight into TPX2-stimulated microtubule assembly [PDF]
, 2017 During mitosis and meiosis, microtubule (MT) assembly is locally upregulated by the chromatin-dependent Ran-GTP pathway. One of its key targets is the MT-associated spindle assembly factor TPX2.

GAP activity, but not subcellular targeting, is required for Arabidopsis RanGAP cellular and developmental functions [PDF]
, 2015 The Ran GTPase activating protein (RanGAP) is important to Ran signaling involved in nucleocytoplasmic transport, spindle organization, and postmitotic nuclear assembly.

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

Analysis of Binding Site Hot Spots on the Surface of Ras GTPase [PDF]
, 2011 We have recently discovered an allosteric switch in Ras, bringing an additional level of complexity to this GTPase whose mutants are involved in nearly 30% of cancers.
