A mitotic kinase scaffold depleted in testicular seminomas impacts spindle orientation in germ line stem cells. [PDF]
, 2015 Correct orientation of the mitotic spindle in stem cells underlies organogenesis. Spindle abnormalities correlate with cancer progression in germ line-derived tumors.

Cytoskeleton, EarlyView.ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

SAS-4 is recruited to a dynamic structure in newly forming centrioles that is stabilized by the gamma-tubulin-mediated addition of centriolar microtubules. [PDF]
, 2008 Centrioles are surrounded by pericentriolar material (PCM), which is proposed to promote new centriole assembly by concentrating gamma-tubulin. Here, we quantitatively monitor new centriole assembly in living Caenorhabditis elegans embryos, focusing on ...

Q&A: Who needs a centrosome? [PDF]
, 2013 The centrosome has several functions. The central one is as the major microtubule organizing center (MTOC) in proliferating animal cells: thus, it helps to organize the microtubules that form the mitotic spindle in dividing cells, and orchestrate a ...

Cytoskeleton, EarlyView.ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Insights into centriole geometry revealed by cryotomography of doublet and triplet centrioles. [PDF]
, 2018 Centrioles are cylindrical assemblies comprised of 9 singlet, doublet, or triplet microtubules, essential for the formation of motile and sensory cilia.

Centriole assembly and the role of Mps1: defensible or dispensable? [PDF]
, 2011 The Mps1 protein kinase is an intriguing and controversial player in centriole assembly. Originally shown to control duplication of the budding yeast spindle pole body, Mps1 is present in eukaryotes from yeast to humans, the nematode C.

Centrioles: Duplicating Precariously [PDF]
Current Biology, 2007 To assemble a mitotic spindle and accurately segregate chromosomes to progeny, a cell needs to precisely regulate its centrosome number, a feat largely accomplished through the tight control of centriole duplication. Recent work showing that the overexpression of centriolar proteins can lead to the formation of multiple centrioles in the absence of pre-

Re-examining the role of Drosophila Sas-4 in centrosome assembly using two-colour-3D-SIM FRAP
eLife, 2015 Centrosomes have many important functions and comprise a ‘mother’ and ‘daughter’ centriole surrounded by pericentriolar material (PCM). The mother centriole recruits and organises the PCM and templates the formation of the daughter centriole. It has been

Identification of novel genes regulating the development of the palate
Developmental Dynamics, EarlyView.Abstract Background The International Mouse Phenotyping Consortium (IMPC) has generated thousands of knockout mouse lines, many of which exhibit embryonic or perinatal lethality. Using micro‐computed tomography (micro‐CT), the IMPC has created and publicly released three‐dimensional image data sets of embryos from these lethal and subviable lines.
