Descriptor English: I-kappa B Proteins
Descriptor Spanish: Proteínas I-kappa B
Descriptor Proteínas B I-kappa
Entry term(s) I-kappa B
Scope note: Familia de proteínas inhibidoras que se unen a las PROTEÍNAS DEL PROTOONCOGÉN REL y modulan su actividad. En el CITOPLASMA, las proteínas B I-kappa se unen al factor de transcripción NF-KAPPA B. La estimulación celular causa su disociación y traslocación del NF-kappa B activo al núcleo.

Scope note: A family of inhibitory proteins which bind to the REL PROTO-ONCOGENE PROTEINS and modulate their activity. In the CYTOPLASM, I-kappa B proteins bind to the transcription factor NF-KAPPA B. Cell stimulation causes its dissociation and translocation of active NF-kappa B to the nucleus.
