CKIδ Decentralizes the Centrosome

submitted by: JCB
When a T cell encounters a target antigen-presenting cell, the lymphocyte's centrosome relocalizes to a specialized contact between the two cells called the immunological synapse. Zyss et al. reveal that casein kinase Iδ helps to reposition the centrosome in activated T cells, perhaps by working with the microtubule plus-end binding protein EB1 to regulate microtubule growth. This biosights episode presents the paper by Zyss et al. from the November 28, 2011, issue of The Journal of Cell...
