Flagellar microtubules do the twist
Pericentrin pivotal in primary cilia he centrosome protein pericentrin acts as an anchor for primary cilia formation in human cells, according to a report by Jurczyk et al. (page 637). The finding further unites the centrosome and primary cilia, both of which are based around centri-oles, and both of which use pericentrin as an anchor for other proteins. The authors show that pericentrin is loc...
متن کاملQuasiparticles do the twist
One of the most memorable lessons of an undergraduate course in quantum mechanics is that identical particles can have two types of “statistics.” An exchange of two identical bosons leaves the many-particle wave function unchanged, while an exchange of two identical fermions introduces a minus sign. The consequences of this minus sign are profound in all areas of physics. Moreover, it has long ...
متن کاملBacterial Sporulation: FtsZ Rings Do the Twist
Formation of the polar Z ring is a crucial step in the establishment of cellular asymmetry during sporulation of Bacillus subtilis. New results suggest that the transition from medial to polar Z rings involves a dynamic FtsZ spiral structure that may transfer FtsZ from medial to polar sites.
متن کاملPhysarum plasmodia do contain cytoplasmic microtubules!
It has been claimed that the plasmodium of the myxomycete Physarum polycephalum constitutes a very unusual syncytium, devoid of cytoplasmic microtubules. In contrast, we have observed a cytoplasmic microtubule network, by both electron microscopy and immunofluorescence in standard synchronous plasmodia, either in semi-thin sections or in smears, and in thin plasmodia, used as a convenient model...
متن کاملHow do kinetochores CLASP dynamic microtubules?
Maintenance of genetic stability during cell division requires binding of chromosomes to the mitotic spindle, a process that involves attachment of spindle microtubules to kinetochores. This enables chromosomes to move to the metaphase plate, to satisfy the spindle checkpoint and finally to segregate during anaphase. Recent studies on the function MAST in Drosophila and its human homologue CLAS...
