Predicted to enable double-stranded DNA binding activity; minor groove of adenine-thymine-rich DNA binding activity; and nucleosomal DNA binding activity. Predicted to be involved in DNA packaging; negative regulation of nucleobase-containing compound metabolic process; and positive regulation of transcription regulatory region DNA binding activity. Predicted to be located in several cellular components, including Golgi apparatus; euchromatin; and nuclear body. Predicted to be part of transcription repressor complex. Predicted to be active in nucleus. Orthologous to human H1-0 (H1.0 linker histone). [provided by Alliance of Genome Resources, Apr 2022]
