    A subclass of Ras proteins that regulate the degradation of IkappaB (2000)

    Publication Date: 2000-02-05
    Description: Small guanosine triphosphatases, typified by the mammalian Ras proteins, play major roles in the regulation of numerous cellular pathways. A subclass of evolutionarily conserved Ras-like proteins was identified, members of which differ from other Ras proteins in containing amino acids at positions 12 and 61 that are similar to those present in the oncogenic forms of Ras. These proteins, kappaB-Ras1 and kappaB-Ras2, interact with the PEST domains of IkappaBalpha and IkappaBbeta [inhibitors of the transcription factor nuclear factor kappa B (NF-kappaB)] and decrease their rate of degradation. In cells, kappaB-Ras proteins are associated only with NF-kappaB:IkappaBbeta complexes and therefore may provide an explanation for the slower rate of degradation of IkappaBbeta compared with IkappaBalpha.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fenwick, C -- Na, S Y -- Voll, R E -- Zhong, H -- Im, S Y -- Lee, J W -- Ghosh, S -- New York, N.Y. -- Science. 2000 Feb 4;287(5454):869-73.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Immunobiology and Department of Molecular Biophysics and Biochemistry, Howard Hughes Medical Institute, Yale University School of Medicine, New Haven, CT 06510, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10657303" target="_blank"〉PubMed〈/a〉

Fullerton The dynamic response of dipole skyrmions in Fe/Gd multilayer films is investigated by ferromagnetic resonance measurements and compared to micromagnetic simulations. We detail thickness- and temperature-dependent studies of the observed modes as well as the effects of magnetic field history on the r… [Phys. Rev. B 95, 224405] Published Mon Jun 05, 2017

Fullerton The interesting physics and potential memory technologies resulting from topologically protected spin textures such as skyrmions have prompted efforts to discover new material systems that can host these kinds of magnetic structures. Here, we use the highly tunable magnetic properties of amorphous F… [Phys. Rev. B 95, 024415] Published Fri Jan 13, 2017
