Nfkbia Gene Summary [Mouse]

Enables transcription regulator inhibitor activity. Involved in B cell receptor signaling pathway; negative regulation of canonical NF-kappaB signal transduction; and positive regulation of transcription initiation by RNA polymerase II. 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; central nervous system; early conceptus; genitourinary system; and naris. Used to study Sjogren's syndrome and atopic dermatitis. Human ortholog(s) of this gene implicated in several diseases, including childhood-onset asthma; ectodermal dysplasia and immunodeficiency 2; hematologic cancer (multiple); hepatitis B; and lung disease (multiple). Orthologous to human NFKBIA (NFKB inhibitor alpha). [provided by Alliance of Genome Resources, Apr 2025]
