Abstract

We previously isolated Aurora-C (Aurkc/Aie1) in a screen for kinases expressed in mouse sperm and eggs. Aurora-C kinase was reported to be a chromosomal passenger protein that plays critical roles in chromosome alignment, segregation, kinetochore-microtubule attachment, and cytokinesis in female mouse meiosis. This chapter describes experimental approaches for examining the subcellular localization and function of Aurora-C kinase during female mouse meiosis, presenting detailed methods for introducing exogenous Aurora-C wild-type and kinase-dead mutant mRNAs into mouse oocytes by cytosolic microinjection, and preparing whole-mount meiotic oocytes and chromosome spreads for confocal immunofluorescence microscopy.
