Transgenic mouse line with green-fluorescent protein-labeled Centrin 2 allows visualization of the centrosome in living cells

Transgenic Res. 2004 Apr;13(2):155-64. doi: 10.1023/b:trag.0000026071.41735.8e.

Abstract

The centrosome plays diverse roles throughout the cellular mitotic cycle and in post-mitotic cells. Analysis of centrosome position and dynamics in living murine cells has been limited due to a lack of adequate reporters and currently requires either cell fixation/immunostaining or transfection with centrosome reporters. Here we describe the generation and characterization of a transgenic mouse line that constitutively expresses green fluorescent protein-labeled Centrin-2 (GFP-CETN2). The phenotype of the mouse is indistinguishable from wild-type and it displays a single pair of fluorescent centrioles in cells of every organ and time point examined. This model will be helpful for visualizing the centrosome in multiple experimental conditions.
