Predicted to enable several functions, including NF-kappaB binding activity; nuclear localization sequence binding activity; and ubiquitin protein ligase binding activity. Acts upstream of or within several processes, including lipopolysaccharide-mediated signaling pathway; negative regulation of Notch signaling pathway; and pattern recognition receptor signaling pathway. Located in cytosol and nucleus. Is expressed in several structures, including alimentary system; early conceptus; genitourinary system; naris; and vibrissa follicle. Used to study Sjogren's syndrome and atopic dermatitis. Human ortholog(s) of this gene implicated in several diseases, including childhood-onset asthma; hematologic cancer (multiple); hepatitis B; hepatitis C; and lung disease (multiple). Orthologous to human NFKBIA (NFKB inhibitor alpha). [provided by Alliance of Genome Resources, Apr 2022]
