MDN1, midasin homolog (yeast) is a protein that in humans is encoded by the MDN1 gene.[5]

Model organisms[edit]

Model organisms have been used in the study of MDN1 function. A conditional knockout mouse line, called Mdn1tm1a(KOMP)Wtsi[10][11] 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.[12][13][14]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[8][15] Twenty four tests were carried out on mutant mice and three significant abnormalities were observed.[8] No homozygous mutant embryos were identified during gestation, and therefore none survived until weaning. The remaining tests were carried out on heterozygous mutant adult mice; females had an increased susceptibility to bacterial infection.[8]
