A Role for the Karyopherin Kap123p in Microtubule Stability [PDF]
Traffic, 2009 Several components of the nuclear transport machinery play a role in mitotic spindle assembly in higher eukaryotes. To further investigate the role of this family of proteins in microtubule function, we screened for mutations in Saccharomyces cerevisiae that confer sensitivity to microtubule‐destabilizing drugs.

Comparative interactomics provides evidence for functional specialization of the nuclear pore complex [PDF]
, 2017 The core architecture of the eukaryotic cell was established well over one billion years ago, and is largely retained in all extant lineages. However, eukaryotic cells also possess lineage-specific features, frequently keyed to specific functional ...

Inhibition of NUPR1–Karyopherin β1 Binding Increases Anticancer Drug Sensitivity [PDF]
International Journal of Molecular Sciences, 2021 Background: Nuclear protein-1 (NUPR1, also known as p8/Com-1) is a transcription factor involved in the regulation of cellular stress responses, including serum starvation and drug stimulation. Methods: We investigated the mechanism of NUPR1 nuclear translocation involving karyopherin β1 (KPNB1), using a single-molecule binding assay and confocal ...

A deficit in zinc availability can cause alterations in tubulin thiol redox status in cultured neurons and in the developing fetal rat brain [PDF]
, 2011 Zinc (Zn) deficiency during early development can result in multiple brain abnormalities and altered neuronal functions. In rats, a gestational deficit of Zn can affect the fetal brain cytoskeleton, and signaling cascades involved in cellular processes ...

Recognition of nuclear targeting signals by Karyopherin-β proteins [PDF]
Current Opinion in Structural Biology, 2010 The Karyopherin-β family of nuclear transport factors mediates the majority of nucleocytoplasmic transport. Although each of the 19 Karyopherin-βs transports unique sets of cargos, only three classes of nuclear localization and export signals, or NLSs and NESs, have been characterized. The short basic classical-NLS was first discovered in the 1980s and

Redox regulation of mammalian sperm capacitation
Asian Journal of Andrology, 2015 Capacitation is a series of morphological and metabolic changes necessary for the spermatozoon to achieve fertilizing ability. One of the earlier happenings during mammalian sperm capacitation is the production of reactive oxygen species (ROS) that will ...

Phylogenetic differences in content and intensity of periodic proteins [PDF]
, 2005 Many proteins exhibit sequence periodicity, often correlated with a visible structural periodicity. The statistical significance of such periodicity can be assessed by means of a chi-square-based test, with significance thresholds being calculated from ...
