Predicted to enable methylated histone binding activity and promoter-specific chromatin binding activity. Predicted to be involved in negative regulation of transcription, DNA-templated. Predicted to act upstream of or within several processes, including ectoderm development; regulation of histone modification; and stem cell proliferation. Predicted to be active in nucleus. Orthologous to human L3MBTL2 (L3MBTL histone methyl-lysine binding protein 2). [provided by Alliance of Genome Resources, Apr 2022]
