Predicted to enable several functions, including DNA-binding transcription repressor activity, RNA polymerase II-specific; histone deacetylase binding activity; and promoter-specific chromatin binding activity. Predicted to be involved in cell fate commitment; regulation of lymphocyte differentiation; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including animal organ development; artery development; and regulation of B cell activation. Predicted to be active in cytoplasm and nucleus. Orthologous to human PRDM1 (PR/SET domain 1). [provided by Alliance of Genome Resources, Apr 2022]
