#Phosphorylation control in #mitosis:
Julie Welburn and colleagues reveal the molecular basis for #cellcycle regulation of #Kif4A and #CENPE motor interaction with #PRC1, needed to organize antiparallel #microtubule bundles and to ensure central spindle integrity, #midbody assembly and #cytokinesis

This week's feature spotlights a novel #microtubule and #actin filament crosslinking #protein involved in the regulation of #phragmoplast organization during #cytokinesis. https://doi.org/10.1111/jipb.13497

Here you have the life-cycle of the #ichthyosporean #Sphaeroforma arctica! A close #animal relative that develops as a #multinucleated #coenocyte in which synchronous rounds of nuclear duplication occur without #cytokinesis, followed by #cellularization and release!

#Micro #filaments are usually about 7 nm in #diameter and #made up of #two #strands of #actin. Microfilament #functions #include #cytokinesis, #amoeboid #movement, #cell #motility, #changes #in #cell #shape, #endocytosis and #exocytosis, #cell #contractility, and #mechanical #stability. #Microfilaments are #flexible and #relatively #strong, #resisting #buckling by #multi #piconewton #compressive #forces and filament #fracture by #nanonewton #tensile #forces.
