Atypical Ras-like protein that may act as a regulator of NF-kappa-B activity. In contrast to other members of the Ras family, the members of the KappaB-Ras subfamily do not contain the conserved Gly and Gln residues in positions 13 and 65, which are replaced by Lys and Val residues, respectively, and are therefore similar to the constitutively active forms of oncogenic forms of Ras. This suggests that members of this family are clearly different from other small GTPases proteins. Belongs to the small GTPase superfamily. Ras family. KappaB-Ras subfamily.
