Nfkbia Gene Summary [Rat]
Enables NF-kappaB binding activity and heat shock protein binding activity. Involved in liver regeneration and response to ethanol. Acts upstream of or within cellular response to cytokine stimulus. Located in cytosol. Part of protein-containing complex. Used to study gastritis; pulmonary emphysema; and sciatic neuropathy. Biomarker of several diseases, including acute necrotizing pancreatitis; alcoholic hepatitis; artery disease (multiple); middle cerebral artery infarction; and toxic shock syndrome. 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]
