Human Y-chromosome gene classification using Fractal Dimension & Shannon Entropy [PDF]

arXiv, 2014
All genes on the human Y-chromosome were studied using fractal dimension and Shannon entropy. Clear outlier clusters were identified. Among these were 6 sequences that have since been withdrawn as CDSs and 1 additional sequence that is not in the current assembly.

Speciation Mediated by Centromeres [PDF]

Developmental Cell, 2013
Speciation accompanies reproductive isolation in natural populations through hybrid sterility or lethality. However, the molecular bases of hybrid lethality are mysterious. In this issue of Developmental Cell, Thomae et al. (2013) demonstrate that Drosophila speciation factors HMR and LHR form a centromeric complex and that increased dosage causes ...

The origin of human chromosome 2 analyzed by comparative chromosome mapping with a DNA microlibrary [PDF]

, 1994
Fluorescencein situ hybridization (FISH) of microlibraries established from distinct chromosome subregions can test the evolutionary conservation of chromosome bands as well as chromosomal rearrangements that occurred during primate evolution and will ...

The PP2A‐B56 Binding Site LxxIxE Contributes to Asp‐Mediated Spindle Pole Stability

Cytoskeleton, EarlyView.
ABSTRACT The organization of microtubules into a mitotic spindle is critical for animal cell proliferation and involves the cooperation of hundreds of proteins whose molecular roles and regulation are not fully understood. The protein product of the Drosophila gene abnormal spindle, Asp, is a microtubule‐associated protein required for correct mitotic ...

Interaction Between Actin and Microtubules During Plant Development

Cytoskeleton, EarlyView.
ABSTRACT The dynamic interaction between actin filaments (AFs) and microtubules (MTs) plays a crucial role in regulating key developmental and physiological processes in plant cells, particularly in the formation of specialized cell types with distinct shapes and functions, such as pollen tubes, trichomes, and leaf epidermal cells.

CENP-A Ubiquitylation Is Inherited through Dimerization between Cell Divisions

Cell Reports, 2016
The presence of chromatin containing the histone H3 variant CENP-A dictates the location of the centromere in a DNA sequence-independent manner. But the mechanism by which centromere inheritance occurs is largely unknown. We previously reported that CENP-

Integrative genomics analysis identifies pericentromeric regions of human chromosomes affecting patterns of inter-chromosomal interactions [PDF]

arXiv, 2014
Genome-wide analysis of distributions of densities of long-range interactions of human chromosomes with each other, nucleoli, nuclear lamina, and binding sites of chromatin state regulatory proteins, CTCF and STAT1, identifies non-random highly correlated patterns of density distributions along the chromosome length for all these features.

Bod1, a novel kinetochore protein required for chromosome biorientation [PDF]

, 2007
We have combined the proteomic analysis of Xenopus laevis in vitro–assembled chromosomes with RNA interference and live cell imaging in HeLa cells to identify novel factors required for proper chromosome segregation. The first of these is Bod1, a protein

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 ...
