Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in aging; response to cytokine; and response to lipopolysaccharide. Located in cytosol and nucleus. Used to study Parkinsonism. Human ortholog(s) of this gene implicated in common variable immunodeficiency. Orthologous to human NFKB2 (nuclear factor kappa B subunit 2). [provided by Alliance of Genome Resources, Apr 2022]
