Ikbkb Gene Summary [Rat]
Enables ATP binding activity. Contributes to IkappaB kinase activity. Involved in several processes, including positive regulation of NF-kappaB transcription factor activity; response to cholecystokinin; and response to lipopolysaccharide. Part of IkappaB kinase complex. Used to study muscular atrophy and pneumonia. Biomarker of Alzheimer's disease; colitis; colon cancer; hypertension; and transient cerebral ischemia. Human ortholog(s) of this gene implicated in several diseases, including breast cancer; combined immunodeficiency (multiple); liver cancer; prostate cancer (multiple); and type 2 diabetes mellitus. Orthologous to human IKBKB (inhibitor of nuclear factor kappa B kinase subunit beta). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Ikbkb often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
