Predicted to be involved in embryonic pattern specification and negative regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including Notch signaling pathway; bone morphogenesis; and somite rostral/caudal axis specification. Predicted to be active in nucleus. Orthologous to human RIPPLY1 (ripply transcriptional repressor 1). [provided by Alliance of Genome Resources, Apr 2022]
