Cell cycle checkpoints in Caenorhabditis elegans: the 14-3-3 gene par-5 is required for germline development and DNA damage response / Checkpoints del ciclo celular en Caenorhabditis elegans: el gen 14-3-3, par-5, es necesario para el desarrollo y respuesta al daño genómico de la línea germinal [PDF]

open access: yes, 2012
[eng] 14-3-3 proteins have been extensively studied from yeast to mammals, and are associated with multiple roles ranging from fundamental processes such as cell cycle, apoptosis and stress response to diseases such as neurodegeneration and cancer ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

14-3-3 Proteins Interact with a Hybrid Prenyl-Phosphorylation Motif to Inhibit G Proteins [PDF]

open access: yes, 2013
Signaling through G proteins normally involves conformational switching between GTP- and GDP-bound states. Several Rho GTPases are also regulated by RhoGDI binding and sequestering in the cytosol.

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

open access: yesFEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Annexin 11 is required for midbody formation and completion of the terminal phase of cytokinesis [PDF]

open access: yes, 2004
Annexins are Ca(2+)-binding, membrane-fusogenic proteins with diverse but poorly understood functions. Here, we show that during cell cycle progression annexin 11 translocates from the nucleus to the spindle poles in metaphase and to the spindle midzone ...

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Protein transduction: A novel tool for tissue regeneration [PDF]

open access: yes, 2002
Tissue regeneration in humans is limited and excludes vitals organs like heart and brain. Transformation experiments with oncogenes like T antigen have shown that retrodifferentiation of the respective cells is possible but hard to control. To bypass the

Adenovirus and its interaction with host cell proteins [PDF]

open access: yes, 2007
The E1B55k gene in adenovirus type 5 was studied by generating recombinant viruses in which the E1B55k gene was N-terminally tagged with either a cyan fluorescent protein (CFP) tag or a tandem affinity purification (TAP) tag.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Expression of cell cycle regulatory proteins cyclin B1, cyclin E, and cdk2 during the first three cell cycles of preimplantation mouse embryo development using indirect immunofluorescence

open access: yes, 1999
The cell cycle is a highly regulated process driven by endogenous factors that have regulatory functions. Certain proteins such as cyclins and cyclin-dependent kinases (cdks) are needed to progress through the four phases of the cell cycle.
