Nuclear Pores: David and Goliath in nuclear transport
Ran is the only known member of the Ras superfamily of small GTP-binding proteins to be localized primarily inside the nucleus, and there is considerable evidence that Ran is closely involved in the traffic of macromolecules into and out of the nucleus [1,2]. Ran has been shown to be an essential factor for nuclear import in digitonin-permeabilized cells, and mutant forms of Ran inhibit both pr...
متن کاملNuclear pores and nuclear assembly.
Communication between the nucleus and cytoplasm occurs through large macromolecular structures, the nuclear pores. Quantitative scanning transmission electron microscopy has estimated the mass of a nuclear pore to be 60 million Daltons in yeast and 120 million Daltons in vertebrates. The past two years were noteworthy in that they saw: 1) the purification of both the yeast and vertebrate nuclea...
متن کاملInhibition of in vitro nuclear transport by a lectin that binds to nuclear pores
Selective transport of proteins is a major mechanism by which biochemical differences are maintained between the cytoplasm and nucleus. To begin to investigate the molecular mechanism of nuclear transport, we used an in vitro transport system composed of a Xenopus egg extract, rat liver nuclei, and a fluorescently labeled nuclear protein, nucleoplasmin. With this system, we screened for inhibit...
متن کاملDynein Recruitment to Nuclear Pores Activates Apical Nuclear Migration and Mitotic Entry in Brain Progenitor Cells
Radial glial progenitors (RGPs) are elongated epithelial cells that give rise to neurons, glia, and adult stem cells during brain development. RGP nuclei migrate basally during G1, apically using cytoplasmic dynein during G2, and undergo mitosis at the ventricular surface. By live imaging of in utero electroporated rat brain, we find that two distinct G2-specific mechanisms for dynein nuclear p...
متن کاملOctagonal Nuclear Pores
Negative staining of isolated nuclear envelopes by phosphotungstate shows that the nuclear pores are octagonal rather than circular. Pores of the same shape and approximately the same width, 663 +/- 5 A, were demonstrated in the newt, Triturus, the frog, Rana, and the starfish, Henricia. The outer and inner diameters of the annulus associated with each pore are respectively greater and less tha...
