Model organisms have been used in the study of TRIM45 function. A conditional knockout mouse line, called Trim45tm1a(KOMP)Wtsi[6][7] 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.[8][9][10]
Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[4][11] Twenty six tests were carried out on mutant mice and three significant abnormalities were observed.[4] 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; males had increased circulating magnesium levels while animals of both sex displayed increased bone strength.[4]
