The regions of expression of Ripply1 and Ripply2, presumptive transcriptional corepressors, overlap at the presomitic mesoderm during somitogenesis in mouse and zebrafish. Ripply1 is required for somite segmentation in zebrafish, but the developmental role of Ripply2 remains unclear in both species. Here, we generated Ripply2 knock-out mice to investigate the role of Ripply2. Defects in segmentation of the axial skeleton were observed in the homozygous mutant mice. Moreover, somite segmentation and expression of Notch2 and Uncx4.1 were disrupted. These findings indicate that Ripply2 is involved in somite segmentation and establishment of rostrocaudal polarity.
