KAP1 is an enigmatic regulatory protein, first described some twenty years ago, shown to be involved in multiple and diverse cellular functions. Specifically, it mediates tasks critical to cell growth and differentiation, pluripotency, apoptosis, gene sile ...
Centrosomes act as the main microtubule-organizing centre of animal cells and play critical roles in the cell, such as mitotic spindle organization, cell polarity, and motility. They are composed of two barrel-shaped structures, the centrioles, surrounded ...
We analyze the collective behavior of hydrodynamically coupled molecular motors. We show that the local fluxes induced by motor displacement can induce the experimentally observed bidirectional motion of cargoes and vesicles. By means of a mean-field appro ...
Centrosomes are the major microtubule organizing centers of animal cells. The two centrosomes present at the onset of mitosis must separate in a timely fashion along the nuclear envelope to ensure proper bipolar spindle assembly and thus genome stability. ...
A robust and reproducible method for culturing monolayers of adherent and well-spread primary islet cells on glass coverslips is required for detailed imaging studies by super-resolution and livecell microscopy. Guided by an observation that dispersed isle ...
The two centrosomes present at the onset of mitosis must separate in a timely and accurate fashion to ensure proper bipolar spindle assembly. The minus-end-directed motor dynein plays a pivotal role in centrosome separation, but the underlying mechanisms r ...
The selectivity and speed of many biological transport processes(1) transpire from a 'reduction of dimensionality'(2) that confines diffusion to one or two dimensions instead of three(3). This behaviour remains highly sought after on polymeric surfaces(4) ...
Aging is a major risk factor for many neurological diseases and is associated with mild cognitive decline. Previous studies suggest that aging is accompanied by reduced synapse number and synaptic plasticity in specific brain regions. However, most studies ...
KRAB-ZFPs constitute the largest family of transcription factors (TFs) encoded by the mouse genome and are known to interact with the co-repressor KAP1. KRAB/KAP1-mediated regulation is essential for several development- and ESC- specific functions, in par ...
Centrioles are conserved microtubule-based organelles with 9-fold symmetry that are essential for cilia and mitotic spindle formation. A conserved structure at the onset of centriole assembly is a "cartwheel" with 9-fold radial symmetry and a central tubul ...
