Nuclear proteins acting on mitochondria

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2011
An important mechanism in apoptotic regulation is changes in the subcellular distribution of pro- and anti-apoptotic proteins. Among the proteins that change in their localization and may promote apoptosis are nuclear proteins. Several of these nuclear proteins such as p53, Nur77, histone H1.2, and nucleophosmin were reported to accumulate in the ...

Modulation of DNA End Joining by Nuclear Proteins*

open access: yesJournal of Biological Chemistry, 2005
DNA double strand breaks in mammalian cells are primarily repaired by homologous recombination and non-homologous end joining (NHEJ). NHEJ may either be error-free or mutagenic with deletions or insertions at the joint.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Hop-on hop-off: importin-a-guided tours to the nucleus in innate immune signaling

open access: yesFrontiers in Plant Science, 2013
Nuclear translocation of immune regulatory proteins and signal transducers is an essential process in animal and plant defense signaling against pathogenic microbes.

Interplay of the nuclear envelope with chromatin in physiology and pathology

open access: yesNucleus, 2020
The nuclear envelope compartmentalizes chromatin in eukaryotic cells. The main nuclear envelope components are lamins that associate with a panoply of factors, including the LEM domain proteins.

In vitro transport of a fluorescent nuclear protein and exclusion of non-nuclear proteins

open access: yesJournal of Cell Biology, 1986
An in vitro system was developed that provides a quick microscopic assay for nuclear transport. The assay uses an extract of Xenopus eggs, normal or synthetic nuclei, and a fluorescently labeled nuclear protein, nucleoplasmin.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
