Protein
NF-kappa-B inhibitor-interacting Ras-like protein 1
Organism
Macaca fascicularis
Function
Atypical Ras-like protein that acts as a potent regulator of NF-kappa-B activity by preventing the degradation of NF-kappa-B inhibitor beta (NFKBIB) by most signals, explaining why NFKBIB is more resistant to degradation. May act by blocking phosphorylation of NFKBIB and mediating cytoplasmic retention of p65/RELA NF-kappa-B subunit. It is unclear whether it acts as a GTPase. Both GTP- and GDP-bound forms block phosphorylation of NFKBIB (By similarity).
Similarity
Belongs to the small GTPase superfamily. Ras family. KappaB-Ras subfamily.
