Primary Antibodies
KappaB ras1 Antibody
Background
KappaB ras-1 (κB-ras-1) and κB-ras-2 are two small proteins that similar to Ras-like small GTPases that associate with IkappaB (IκB), an inhibitor of the transcription factor NF-κB. IκB exists in two homologous forms, IκB-α and IκB-β, although IκB-β contains a unique 47-amino acid region within its ankyrin domain. While inactive IκB-α-NF-κB complexes can shuttle in and out of the nucleus, IκB-β-NF-κB complexes are retained exclusively in the cytoplasm. It is suggested that κB-ras proteins preferentially bind to the IκB-β form through this unique insert within the ankyrin region, thus modulating the cellular location of IκB-β and regulating the rate of degradation of IκB-β. This antibody is specific for κB-ras1 and has no cross-reactivity to κB-ras2.
