Recombinant Human NF-kappa-B inhibitor-interacting Ras-like protein 1 (NKIRAS1)

Uniprot Id

Q9NYS0

Target Species

Human

Target Name

NKIRAS1

Target Full Name

NF-kappa-B inhibitor-interacting Ras-like protein 1

Target 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.

Target Subcellular Location

Cytoplasm.

Target Protein Families

Small GTPase superfamily, Ras family, KappaB-Ras subfamily

Target Tissue Specificity

Widely expressed.

Target Background

Predicted to enable GTPase activating protein binding activity. Predicted to be involved in I-kappaB kinase/NF-kappaB signaling. Predicted to act upstream of or within several processes, including Ral protein signal transduction; lung alveolus development; and surfactant homeostasis. Located in cytosol and endoplasmic reticulum.
