Protein Jumonji is a protein that in humans is encoded by the JARID2 gene.

This gene is an ortholog of the mouse Jarid2 gene, which encodes a nuclear protein essential for mouse embryogenesis, including neural tube formation. Overexpression of the mouse gene negatively regulates cell proliferation. The jumonji proteins contain a DNA-binding domain, called an AT-rich interaction domain (ARID), and share regions of similarity with human retinoblastoma-binding protein-2 and the human SMCX protein.

Model organisms have been used in the study of JARID2 function. A conditional knockout mouse line, called Jarid2^{tm1a(KOMP)Wtsi} 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 — at the Wellcome Trust Sanger Institute.

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Twenty six tests were carried out and two phenotypes were reported. Homozygous mutant embryos were identified during gestation but almost half showed signs of oedema, and in a separate study, only 1% survived until weaning (significantly less than the Mendelian ratio). The remaining tests were carried out on heterozygous mutant adult mice; no significant abnormalities were observed in these animals.
