Predicted to enable several functions, including nucleic acid binding activity; promoter-specific chromatin binding activity; and transcription corepressor binding activity. Involved in several processes, including histone H3-K27 trimethylation; negative regulation of macromolecule metabolic process; and response to retinoic acid. Predicted to be located in nuclear body; nucleolus; and sex chromatin. Predicted to be part of nucleus; protein-DNA complex; and ribonucleoprotein complex. Biomarker of spina bifida. Orthologous to human SUZ12 (SUZ12 polycomb repressive complex 2 subunit). [provided by Alliance of Genome Resources, Apr 2022]
