NF-κB inhibitor interacting Ras-like 2 is a protein that in humans is encoded by the NKIRAS2 gene.[1]

Model organisms[edit]

Model organisms have been used in the study of NKIRAS2 function. A conditional knockout mouse line, called Nkiras2tm1a(EUCOMM)Wtsi[4][5] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[6][7][8]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[3][9] Twenty one tests were carried out, but no significant abnormalities were observed.[3]
