NF-kappa-B inhibitor alpha (Q9Z1E3)

Uniprot ID Q9Z1E3
Protein Name NF-kappa-B inhibitor alpha
Gene Name Nfkbia
Species Mus musculus (Mouse)
Signal peptide(a) N Secretome P(b) 0.704
Function Inhibits the activity of dimeric NF-kappa-B/REL complexes by trapping REL dimers in the cytoplasm through masking of their nuclear localization signals. On cellular stimulation by immune and proinflammatory responses, becomes phosphorylated promoting ubiquitination and degradation, enabling the dimeric RELA to translocate to the nucleus and activate transcription. .

(a) The Signal peptide D-score cutoff for "YES"(having signal peptide) is 0.45.
(b) Non-classically secreted proteins should obtain an NN-score(Neural Networks score) exceeding the normal threshold of 0.5, but not at the same time be predicted to contain a signal peptide.
