Feedback regulation of Ran gene expression by Ran protein

Gene, 2011
Ran, an abundant GTPase that is highly conserved in eukaryotes from yeast to human, has been implicated in many aspects of nuclear structure and function. Recently it is revealed that the Ran GTPase can regulate the hemocytic phagocytosis of shrimp by interaction with myosin. However the regulation of Ran gene expression remains unknown. In this study,

The Ran decathlon: multiple roles of Ran

Journal of Cell Science, 2000
ABSTRACT The Ran GTPase system affects many cellular processes, including the regulation of cell cycle progression, nuclear envelope structure and function, and nucleocytoplasmic transport. The biochemical basis for the involvement of Ran in nuclear import and export has been well documented, but the direct targets of Ran in other ...

Ran Regulation by Ran GEF and Ran GAP

2001
The Ras-related GTPase Ran was first isolated as a complex with the chromatin-associated protein RCC1 (Bischoff and Ponstingl, 1991a), which turned out to be its guanine nucleotide exchange factor (GEF; Bischoff and Ponstingl, 1991b). Ran was mainly found in the nucleus and hence was designated the Ras-related nuclear protein.

Ran at kinetochores

Biochemical Society Transactions, 2006
The Ran GTPase controls many cellular functions, including nucleocytoplasmic trafficking, spindle assembly, nuclear assembly and cell-cycle progression. Considerable evidence suggests that diffusible Ran-GTP near mitotic chromatin facilitates the release of critical factors from nuclear transport receptors, thereby promoting organization of mitotic ...

Joint RAN/backhaul optimization in centralized 5G RAN

2015 European Conference on Networks and Communications (EuCNC), 2015
This paper provides an overview of joint radio access network (RAN) and backhaul (BH) optimization methods in dense small cell networks, assuming a heterogeneous backhaul and centralization by Cloud RAN. The main focus is on the design of novel MAC (medium access control) and RRM (radio resource management) schemes for constrained, non-ideal backhaul ...

RAN translation down

Nature Neuroscience, 2019
Repeat-associated non-AUG (RAN) translation generates toxic repeat proteins from pathological repeat expansions found in certain neurodegenerative disorders, including amyotrophic lateral sclerosis and frontotemporal dementia. How to suppress RAN translation has so far been unknown.
