Involved in somite rostral/caudal axis specification. Acts upstream of or within several processes, including Notch signaling pathway; bone morphogenesis; and post-anal tail morphogenesis. Predicted to be active in nucleus. Is expressed in embryo mesoderm; paraxial mesenchyme; and tail bud. Used to study spondylocostal dysostosis. Human ortholog(s) of this gene implicated in spondylocostal dysostosis. Orthologous to human RIPPLY2 (ripply transcriptional repressor 2). [provided by Alliance of Genome Resources, Apr 2022]
