General Information
Term I-kappaB phosphorylation ID (Ontology) GO:0007252 (Gene Ontology)
Definition The process of introducing a phosphate group into an inhibitor of kappa B (I-kappaB) protein. Phosphorylation of I-kappaB targets I-kappaB for ubiquitination and proteasomal degradation, thus releasing bound NF-kappaB dimers, which can translocate to the nucleus to bind DNA and regulate transcription.[ PubMed:21772278 PubMed:7594468 ]
Also Known As "IkappaB phosphorylation" ; "IKB phosphorylation" ; "inhibitor of kappaB phosphorylation" (for all, see Synonyms field below)
