NFKB inhibitor interacting Ras-like 2 (NKIRAS2), also known as KBRAS2, is similar to the Ras-like small GTPases that associate with IkappaB. These Ras-like proteins, NKIRAS1 and NKIRAS2, interact with the PEST domains of IkBa and IkBb and decrease their rate of degradation. NKIRAS2 shows 71% identity to KBRAS1. NKIRAS2 is an inhibitor of the transcription factor NF-kappaB. Recombinant protein corresponding to aa1-191 from human NKIRAS2, fused to His-tag at N-terminal expressed in E. coli.
