Predicted to enable several functions, including FAD binding activity; histone H3-di/monomethyl-lysine-4 FAD-dependent demethylase activity; and zinc ion binding activity. Predicted to be involved in negative regulation of transcription by RNA polymerase II; positive regulation of transcription by RNA polymerase II; and regulation of DNA methylation. Predicted to act upstream of or within DNA methylation involved in gamete generation; histone H3-K4 demethylation; and regulation of gene expression by genetic imprinting. Predicted to be located in nucleoplasm. Predicted to be part of nucleosome. Orthologous to human KDM1B (lysine demethylase 1B). [provided by Alliance of Genome Resources, Apr 2022]
