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