Predicted to enable nucleic acid binding activity. Predicted to be involved in apoptotic chromosome condensation; negative regulation of mRNA splicing, via spliceosome; and positive regulation of apoptotic process. Predicted to act upstream of or within apoptotic process. Located in nucleolus. Is expressed in several structures, including central nervous system; connective tissue; early conceptus; olfactory epithelium; and retina. Orthologous to human ACIN1 (apoptotic chromatin condensation inducer 1). [provided by Alliance of Genome Resources, Apr 2022]
