The 3' to 5' exoribonuclease DIS3: from structure and mechanisms to biological functions and role in human disease [PDF]

, 2015
DIS3 is a conserved exoribonuclease and catalytic subunit of the exosome, a protein complex involved in the 3’ to 5’ degradation and processing of both nuclear and cytoplasmic RNA species.

Methods for Controlling Small GTPase Activity

ChemBioChem, Accepted Article.
Small GTPases comprise a diverse class of signaling proteins in mammalian cells and regulate a variety of cellular processes such as cell growth, cell movement, vesicle formation, and nuclear transport. Due to their involvement in critical cellular pathways, changes in the activation state of small GTPases due to genetic mutations or alterations in ...

Transcriptionally inactive oocyte-type 5S RNA genes of Xenopus laevis are complexed with TFIIIA in vitro [PDF]

, 1987
An extract from whole oocytes of Xenopus laevis was shown to transcribe somatic-type 5S RNA genes approximately 100-fold more efficiently than oocyte-type 5S RNA genes.

Chromenone derivatives as CRM1 Inhibitors for Targeting Glioblastoma

ChemBioChem, Accepted Article.
Glioblastoma (GBM) is one of the most aggressive and deadly cancers. Due to the complexity and redundancy within signaling networks in GBM, targeted inhibitors of specific pathways have shown only limited success. The nuclear export receptor Chromosome Region Maintenance 1 (CRM1) has recently emerged as a promising therapeutic target, as its inhibition

A small nuclear GTP-binding protein from tomato suppresses a Schizosaccharomyces pombe cell-cycle mutant.

Proceedings of the National Academy of Sciences of the United States of America, 1994
Ran is a 25-kDa Ras-related nuclear GTP-binding protein which is very highly conserved in humans, Saccharomyces cerevisiae, and Schizosaccharomyces pombe. Ran has been found to form a stable, noncovalent complex with the chromatin-associated protein RCC1,

ARHI (DIRAS 3), an Imprinted Tumor Suppressor Gene, Binds to Importins, and Blocks Nuclear Translocation of Stat3 [PDF]

, 2008
ARHI (DIRAS3) is an imprinted tumor suppressor gene whose expression is lost in the majority of breast and ovarian cancers. Unlike its homologs Ras and Rap, ARHI functions as a tumor suppressor.

Mechanism of how augmin directly targets the γ-tubulin ring complex to microtubules [PDF]

, 2018
Microtubules (MTs) must be generated from precise locations to form the structural frameworks required for cell shape and function. MTs are nucleated by the γ-tubulin ring complex (γ-TuRC), but it remains unclear how γ-TuRC gets to the right location ...

Selective [9‐15N] Guanosine for Nuclear Magnetic Resonance Studies of Large Ribonucleic Acids

ChemBioChem, EarlyView.
The small chemical shift anisotropy of nitrogen‐15 at the 9‐position in guanine (15N9‐G) leads to long T2 values and narrow NMR lines, particularly attractive to probe structure and dynamics of large (>200 nucleotide) ribonucleic acids (RNAs). RNAs regulate various cellular processes using malleable 3D structures, and understanding the factors that ...

Atypical Rho GTPases of the RhoBTB Subfamily: Roles in vesicle trafficking and tumorigenesis [PDF]

, 2016
RhoBTB proteins constitute a subfamily of atypical Rho GTPases represented in mammals by RhoBTB1, RhoBTB2, and RhoBTB3. Their characteristic feature is a carboxyl terminal extension that harbors two BTB domains capable of assembling cullin 3-dependent ...

PLK4: Master Regulator of Centriole Duplication and Its Therapeutic Potential

Cytoskeleton, EarlyView.
ABSTRACT Centrosomes catalyze the assembly of a microtubule‐based bipolar spindle, essential for the precise chromosome segregation during cell division. At the center of this process lies Polo‐Like Kinase 4 (PLK4), the master regulator that controls the duplication of the centriolar core to ensure the correct balance of two centrosomes per dividing ...
